2011-01-29  Carsten Haitzler (The Rasterman)

        1.0.0 release

2011-01-29  Carsten Haitzler (The Rasterman)

        * Enabled mempool for object allocation
        * Allow shorter pre-render handler for rect objects if they are
          invisible

2011-01-30  Tom Hacohen (TAsn)

        * It's actually a merge from my local branch upstream so this
          includes many changes.
        * Fixed cursor/selection handling with BiDi text.
        * Fixed many BiDi issues in both textblock and text objects.
        * Cleaned up textblock and font engine a lot.
        * Added auto-alignment to tetxblock and text objects.
        * Added mixedwrap (word wrap, and if a word is too big cut it) support
          to textblock.
        * Renamed a lot of stuff.
        * Made textblock faster, mostly by saving item sizes and caching
          layout items when text doesn't change.
        * Added harfbuzz (ot layouting/shaping and etc) support.
        * Currently you need to set the env var EVAS_USE_OT to '1' in order to
          use OT support (harfbuzz) that will change soon.
        * More code cleanups will be coming in the future. This shipment is
          mostly to get code review started (and also make sure I don't have a
          merging hell later on).

2011-01-31  ChunEon Park

        * Fix lurking free bug in key grabs.


2011-02-01  Carsten Haitzler (The Rasterman)

        * Added WBMP loader thanks to Samsung.

2011-02-01  Tom Hacohen (TAsn)

        * Started using string objects instead of strings in most of the
          font engine (everywhere except draw). Haven't removed the
          paramteres yet, but did mark them as UNUSED. Removing them will be
          part of a future change.
        * Removed run-time OT toggling support, OT is now fast, no need for that.
        * Renamed all of the intl_props->text_props (because it really
          changed purpose
        * Fixed spliting/merging of text_props to be fast and good, not
          hacky and complex like before.
        * Added "mirrored mode" to table object.

2011-02-07 Brett Nash (nash@nash.id.au)

        * Proxy Objects; Now you can set an image to have a 'source' of
          another object.  The proxy will display the object as well.  Proxy
          objects should be mostly complete.
        * Proxy objects should be complete; please report and bugs to me.
        * Partial support for arbitrary clipping.  Final support coming soon
          (with some other changes).  You can set most objects as a clip on
          other objects.  This will use the alpha channel of the object as a
          clip on the object.  This is still buggy.
        * CLIPPING DISABLED AND REMOVED DUE TO BEING TOO BUGGY AND INCOMPLETE *
        * Software support for arbitrary maps.  So you can use any size map
          (not just 4 points) for maps.  Once again this is a little buggy.
        * ARBITRARY MAPS DISABLED AND REMOVED DUE TO BEING TOO BUGGY AND INCOMPLETE *

2011-02-02  Carsten Haitzler (The Rasterman)

        * GL engine gets a speculative texture cache to shadow the
          normal image cache to avoid excess texture uploads when
          cycling images often. Should improve performance in some
          cases.

2011-02-12  Carsten Haitzler (The Rasterman)

        * Fix "ridiculous scaling size" bug, where scaling images to
          sizes like 1 billion pixels high or wide caused evas to try
          allocate scaletables on the stack and the stack just couldn't
          handle it. Now it only allocates a table for the visible
          region which will always be sane, and even has insanity
          checks now. At worst you'll get an unrendered image if the
          values are silly and some slowness. No crashes.

2011-02-13  Brett Nash (nash@nash.id.au)

        * Fix crash when deleting proxies.  This _technically_ breaks
          evas engines which realloc engine data when a border is set.
          Practically no engines do this.  There is a comment there (and
          if the engine does that border set won't work), in which case
          a more complex work-around is possible.

2011-02-14  Tom Hacohen (TAsn)

        * Added a newline character mode API to textblock. This lets us set
          the newline behavior to either normal (i.e only break a line, not
          a paragraph) to "behave as a PS" mode. Default is the latter.
          The former is the more correct approach but I guess everything else
          is in e is not yet ready to use it. These API should help with the
          transition.
        * A lot of textblock speed improvements and reduced memory footprint.

2011-02-16  Jeonghyun Yun

        * Patch from Jeonghyun Yun <jh0506.yun@samsung.com> that
          improves BMP loader support to handle malformed RLE BMP's that
          encode more pixels per line than the image actuall has.

2011-02-16  Tom Hacohen (TAsn)

        * Dropped Evas_Encoding and moved to use Eina_unicode_utf8 instead.
        * Started showing the unicode replacement character instead of missing
          glyphs.

2011-02-20  Carsten Haitzler (The Rasterman)

        * Fix bug in font string parsing that can result in a crash if a
          font element is long enough.
        * Fix convert rgba8888 -> a8 bug so it wont crash.

2011-02-21  Carsten Haitzler (The Rasterman)

        * Fixed bug with memory access of old utf8 string when
          comparing prev and cur state with text obj.

2011-02-22  Tom Hacohen (TAsn)

        * Fixed a bug in textblock cursor position with empty textblocks.

2011-02-22  Carsten Haitzler (The Rasterman)

        * Fixed bug smart calc array where it'd nuke the array when nested
          process calls happen and leave some objects uncalculated, but
          removed from the array and marked as needing a calc thus never
          getting back into the array.

2011-02-27  Vincent Torri

        * Fixed static linking of the bmp, wbmp and tga loaders

2011-03-07  Mike Blumenkrantz

        * Fix segv when trying to set gl viewpoint with NULL ctx

2011-03-08  Carsten Haitzler (The Rasterman)

        * Fix problem with different x vsync api between SGI and EXT flavor
        as they have the same base name, but different prototypes
        * Add evas_object_ref() and evas_object_unref() to defer
        deletion of objects until all references are removed

2011-03-09  Carsten Haitzler (The Rasterman)

        * Fix bug with evas_object_del() calling DEL callback BEFORE
        the HIDE one.

2011-03-10  Sung W. Park

        * Fix bug with yinvert handling of native surfaces.

2011-03-10  Carsten Haitzler (The Rasterman)

        * Fix issue with loading alpha BMP's with "check if all pixel alpha
        are 0 or not and then force alpha off if all are 0". This
        means you can never have a 100% empty/transparent BMP though
        in 32bpp mode.

2011-03-11  Carsten Haitzler (The Rasterman)

        * Add ICO loader to evas (also can load CUR cursor files in theory)

2011-03-14  Carsten Haitzler (The Rasterman)

        * Add "load from memory" API: evas_object_image_memfile_set() by
        popular demand. Can load an image format from a memory address.

2011-03-15  Cedric BAIL

        * Fix issues with clipping and map.

2011-03-18  Jiyoun Park

        * Fix wrong call to free when using mempool for Evas_Object.

2011-03-19  Carsten Haitzler (The Rasterman)

        * Caching and timestamp checker for image files made much more
        pedantic and it checks not just modified timestamp but also
        inode number, size, and on linux, the nanonsecond resolution
        timestamp as well.

2011-03-19  Brett Nash (nash)

        * Proxy: Bypass the clip on smart clipped objects.  This is probably
        what you want if you are using proxies, as it means clips don't cause
        the object to be invisible by the proxy.

2011-03-22  Gustavo Sverzut Barbieri (k-s)

        * Fix build of GL and static modules.
        * Fix ico loader static build.

2011-03-30  Tom Hacohen (TAsn) and Carsten Haitzler (The Rasterman)

        * Added vertical alignment support to textblock.
          API: evas_object_textblock_valign_set/get

2011-04-04  Sung W. Park

        * Added Evas OpenGL interface to be able to get an OpenGL API for
        rendering to image objects. This is the beginning so not
        totally functional yet.

2011-04-05  Cedric Bail

        * Remove Evas Quartz backend.
        * Remove Evas Cairo backend.
        * Remove Evas Qtopia backend.
        * Remove Evas Xrender backend.

2011-04-06  Carsten Haitzler (The Rasterman)

        * Fix bug in GL engine with someone stealing the GLX context away
        as well as scissor clips when rotated output is not 0 (90, 180, 270).

2011-04-07 Tom Hacohen (TAsn)

        * Textblock: Major speed improvements.
        * Textblock: Only relayout and remake paragraphs that have actually
          changed. This means we are a lot faster than before, especially with
          long texts.

2011-04-10 Tom Hacohen (TAsn)

        * Textblock: Fixed a bug in evas_object_textblock_text_markup_prepend
          that caused it to use the object's cursor instead of the cursor
          passed.

2011-04-11  Carsten Haitzler (The Rasterman)

        * Feature: Text & Textblock - Add 8 explicit shadow directions for
        text style effects.

2011-04-12 Myoungwoon Roy Kim (roy_kim)

        * Font-engine: Added runtime italic (actually slanting) and
          emboldening. - Automatically slants/emboldens a font at runtime if
          italic/bold/crusiva and etc are requested but not found in the
          system.

2011-04-14 Tom Hacohen (TAsn)

        * Font-engine: Implemented higher level override API for the bidi
          functions. This implements clause HL4 of the bidi algorithm.
          This is very cool actually, it lets us to force-separate paragraphs
          so each part will get his bidi calculated on it's own. This is very
          useful for "to" field of email/sms applications where ',' is used to
          separate different text entities.

2011-04-19 Brett Nash (nash)

        * Filters: So filtering of various flavours.  They work only on images
          (use a proxy if you want it on other objects).  Documentation inline.
          Supports a filter object or filter under (the area where the object
          is filtered).  Various parameters to tweak, and potential for
          additional filters (but you get to write the shader ;-)
        * FILTERS DISABLED AND REMOVED DUE TO BEING TOO BUGGY AND INCOMPLETE *

2011-04-24 Thierry el Borgi

        * Add PSD file format support.

2011-04-26  Carsten Haitzler (The Rasterman)

        * Added "generic" image loader that can just execute some command
        to load any given file format and read the RGBA data as stdout
        from the command, or from an intermediate temporary file or
        shared memory segment the executable loader provides. Evas
        doesn't care about the loader beyond it providing output via
        stdout to define image parameters (size, alpha channel and data
        information), and evas will call a specific loader binary
        based on extension name of srouce file. This allows for evas to
        load image data from files where the loader may be prone to
        instability, or require use of libraries that are GPL or
        otherwise undesirable in terms of the result to applications
        using evas. So basically, if you want a GPL loader or have a
        very unstable one, write a loader binary and call it
        evas_image_loader.extension e.g. evas_image_loader.pdf or
        evas_image_loader.xcf or evas_image_loader.xcf.gz etc. etc.

2011-04-28 Shilpaonkar Singh

        * Textblock: Add "password" tag to turn on/off password in the middle
          of the textblok. Especially useful for implementing "show last char"
          for password entries.

2011-05-04  Carsten Haitzler (The Rasterman)

        * Improved table layout for homogenous mode to handle not column
        or row multiple sized table better.

2011-05-04  Jiyoun Park

        * OpenGL binary shader ability to cache (save and load back
        later) to avoid re-compiling shaders on every time an app starts and
        uses the GL engine. Faster startup time.

2011-05-04 Tom Hacohen (TAsn)

        * Textblock: Do standard compliant line breaks. In order to achieve
          that we now statically link against liblinebreak (available in
          src/static_deps/liblinebreak). It's usage can be disabled using the
          configure flag: "--disable-liblinebreak"; Disabling it will activate
          the fallback line breaking methods which are not very correct, but
          are possibly faster. I haven't noticed any difference between the
          two speed-wise, but there probably are in some rare cases.

2011-05-06 Cedric Bail

        * Don't try all image loader when user is pointing them on a directory.

2011-05-11  Carsten Haitzler (The Rasterman)

        * Fix problem with Evas engine not calling pre/post swap functions
        in the GL engine when using EGL/OpenGL-ES2
        * Fix SVG loader 2 phase loader having differing scale down code
        for first and 2nd phase. Resulted in crash when loading some SVGs

2011-05-11 Tom Hacohen (TAsn)

        * Textblock: Added evas_textblock_node_format_list_get. This is very
          useful for edje_entry that uses anchors in the text.

2011-05-12  Carsten Haitzler (The Rasterman)

        * Add smart instance usage count get function for ability to free
        data from memory from a smart class if needed.

2011-05-12 Brian Wang

        * Textblock: fix segfault with evas_textblock_cursor_content_get

2011-05-12  Carsten Haitzler (The Rasterman)

        * Add a smart "Grid" layout object that lays out objects in a regular
        "virtual resolution" grid (eg 100x100) so you can lay them out
        as a "scaled percentage" of the virtual resolution. virtual
        resolution is defineable as is the geometry of each member.

2011-05-18  Sung W. Park

        * Fix some internal stencil and depth requests for OpenGL-ES2
        due to OpenGL-ES limitations.
        * Fix Surface recreation for FBO in Evas GL support.

2011-05-23  Vincent Torri

        * Fix compilation with libjpeg 8 on Windows.

2011-05-24  Cedric Bail

        * Use Eina_File when possible.

2011-05-26  Carsten Haitzler (The Rasterman)

        * Fix Evas table to handle weighting correctly for items and veto
        rows or columns that have any child spanning that column not
        able to expand.
        * Fix Evas table to use actual fractional weights, not just
        boolean expand/not expand from weight value.

2011-05-27  Carsten Haitzler (The Rasterman)

        * Add evas_event_thaw_eval() for conveneince of evaluating in state
        and callbacks of the pointer after a thaw is complete.

2011-05-29  Tom Hacohen (TAsn)

        * Font-engine: Fixed a bug in glyph search causing inconsistent return
          values. The found fi should always be NULL if there was no fi found.

2011-05-29  Tom Hacohen (TAsn)

        * Font-engine: Conform to the API changes in Harfbuzz 0.6.0

2011-05-29  Raoul Hecky

        * Textblock: Added support for numeric escape codes. e.g "&#x3c;".

2011-05-29  Vincent Torri

        * Fix compilation when --disable-async-preload is passed to configure.

2011-06-01  Cedric Bail

        * Add +evas_object_image_extension_can_load_get and
        evas_object_image_extension_can_load_fast_get that check if a file
        may be opened by Evas_Object_Image.

2011-06-07  Cedric Bail

        * Use Eina_File for JPEG loader.
        * Add evas_object_image_load_orientation_get and evas_object_image_load_orientation_set,
        that tell if we should honor the orientation information when loading image file.

2011-06-17  Carsten Haitzler (The Rasterman)

        * Allow evas table to re-pack the same object without error and just
        update packing parameters
        * Allow to get packing location of table child

2011-06-28  Tom Hacohen (TAsn)

        * Polygon: Implemented "is_inside".

2011-07-05  Hyoyoung Chang

        * Fix bug where event causes event in callback on same object, but
        with same event counter, so also filter out same event types.

2011-07-06  Carsten Haitzler (The Rasterman)

        * Fix bug in grab counting on object hide while events are frozen

2011-07-07  Cedric Bail

        * Fix infite loop when reinserting object during recalc stage.

2011-07-27  Tom Hacohen (TAsn)

        * Textblock: Closing tags formats is now well-defined for complex
          formats.
          For example: <font=Sans font_size=23 color=#FFF> should now be
          closed with </font> (or, like before, with the generic poper).
        * Textblock: Add support for out-of-order tag openers/closers.
          Markup sequences like <b><i></b></i> are now legal and work as
          expeceted.

2011-07-28  Tom Hacohen (TAsn)

        * Textblock: Added support for quoting format parameters.
          Formats like: <font='Sans' color='#FFF'> are now legal.
        * Textblock: Added font_weight and font_style formats.
          These format allow overriding the font style set using:
          font=':style=Bold'.

2011-07-31  Tom Hacohen (TAsn)

        * Textblock: Added font_width.
          This allows overriding the font width set using:
          font=':style=Condensed'

2011-08-01  Tom Hacohen (TAsn)

        * Textblock: Added lang to markup to set the lang of the text.

2011-08-09  Tom Hacohen (TAsn)

        * Textblock: Added evas_textblock_cursor_range_formats_get which
        returns the formats inside a range.
        * Textblock: Added evas_textblock_cursor_visible_range_get which
        updates the cursors to the ends of the area currently visible on
        screen.

2011-08-17  Tom Hacohen (TAsn)

        * Callbacks: Added priority support to callbacks.

2011-08-23  Cedric Bail

        * Fix evas_object_image_data_convert.
        * Add YUV 601 input format to evas_object_image_data_convert.

2011-08-29  Cedric Bail

        * Add colorspaces NV12 and MT12 (64 * 32 macro block tiled
        format, see Linux videodev documentation for more information).

2011-10-17  Shilpa Singh

        * Textblock: Added underline=dashed support.
        Tag changes:
         - dashed is a legal value for underline
        New tags:
         - underline_dash_color
         - underline_dash_width
         - underline_dash_gap

2011-10-21  Carsten Haitzler (The Rasterman)

        * Add function to request what the largest possible image (or texture)
        size is from evas.

2011-10-27  ChunEon Park (Hermet)

        * Add evas_object_freeze_events_set/get to discard the object events.
        they will be useful some cases such as transition.

2011-11-02  Nicolas Aguirre
        * Add gl_cocoa engine

2011-11-16  Carsten Haitzler (The Rasterman)

        * JPEG encode and decode in eet now uses ISLOW (not IFAST) due to
        noticable quality losses in the chase for speed. It will use
        IFAST for quality less than 60 when encoding

2011-11-20  Carsten Haitzler (The Rasterman)

        * TGA loader gets fixed alpha decode - real life tga's have
        proper alpha values. also reduce false positive tga file
        detection

2011-11-24  Carsten Haitzler (The Rasterman)

        * Fix repeat event inheritance from parent smart just like
        pass events are inherited. This was inconsistent.

2011-12-02 Carsten Haitzler (The Rasterman)

        1.1.0 release

2011-12-07  Carsten Haitzler (The Rasterman)

        * Fix build if gcc too old - if immintrin.h doesn't exist,
        don't enable SSE3.

2011-12-08  Tom Hacohen (TAsn)

        * Textblock markup: Support self closing format tags, i.e <br/>.
        You should use <br/> and not <br>. The latter still works but it's use
        is discouraged.
        * Textblock: Added evas_textblock_text_markup_to_utf8.
        This lets you convert textblock markup to plain text.
        This converts formats and everything correctly.

2011-12-12  Carsten Haitzler (The Rasterman)

        * Fix rounding error in map clip bounds calculation

2011-12-12  Tom Hacohen (TAsn)

        * Textblock: Added evas_textblock_cursor_word_start/end.
        Those functions let you jump to the start/end of the word under the
        cursor.

2011-12-13  Carsten Haitzler (The Rasterman)

        * Fix grab count negative values if you do weird combinations of
        press and release with multiple fingers or multiple mouse
        buttons.

2011-12-14  Cedric BAIL

        * Use Eina_File when loading bmp, ico, pmaps and wbmp files.
        * Fix potential race condition in wbmp loader code.

2011-12-14  Tom Hacohen (TAsn)

        * Textblock: Made "br" and "tab" default tags for newline and tab.
        * Textblock: Added "b" and "i" as default tags that can be overridden
        by style, and added the infra to support this.
        * Textblock: Added evas_textblock_text_utf8_to_markup

2011-12-16  Carsten Haitzler (The Rasterman)

        * Fix clip bug that shows up in buffer engine
        * Fix SSE3 routines with buggy output - disable
        * Add new api to set and get default event flags.

2011-12-19  Carsten Haitzler (The Rasterman)

        * Add new canvas events called just before and after evas rendering
        starts and stops.

2011-12-21  ChunEon Park (Hermet)

        * Events: repeat events should not be affected by children.
        Fixed to object passes events to the next object in the same layer
        if the repeat_events is enabled.

2011-12-23 Sanghee Park

        * Extend pixman support to allow other operations to use
          pixman when doing software rendering. On x86 this isn't useful
          but on ARMv7 with NEON pixman happens to do better with image
          blending and nearest scale blending.
        * Add tiled rotator for 32bit display as an option.

2011-12-26  Christopher Michael (devilhorns)

        * Add functions to get/set if an object is a 'frame_object'

2011-12-27  Carsten Haitzler (The Rasterman)

        * Add feature to get number of pressed devices (help fix
          ecore-evas bug).

2011-12-28  Carsten Haitzler (The Rasterman)

        * Add recursive name find function - evas_object_name_child_find()

2012-01-01  Carsten Haitzler (The Rasterman)

        * Improve CPU use on nvidia drivers when vsyncing. It was
          actually glXWaitGL() spinning, not glXSwapBuffers(), so this
          points to a bug in the nvidia drivers where the sleep logic
          in glXSwapBuffers() hasn't been transferred to glXWaitGL().
          Avoid use of glXWaitGL() to avoid the nvidia bug.

2012-01-02  Cedric Bail

        * Fix unitialized value when running generic loader without any
        application found to open the file.
        * Use Eina_File when openning XPM file.

2012-01-03  Cedric Bail

        * Use Eina_File for PSD file to.

2012-01-06  Sung W. Park (sung_)

        * Add EvasGL support to software backend using OSMesa.  Requires OSMesa
          library.  Due to caveats in OSMesa, surface config stays with a
          context rather than with a surface.  So for now, the config of a
          surface remains with the first context that it binds to.  May need
          to come up with a different solution in the near future.

2012-01-12  Sung W. Park (sung_)

        * Add new api evas_gl_config_new/free() to ensure backward compatibility.
          Previously, the user simply declared a Evas_GL_Config object but this
          can cause issues if new configs are added. Now we have evas allocate it
          for you.

2012-01-16  Raphael Kubo da Costa (rakuco)

        * Add evas_object_smart_callback_del_full() to allow users to
        unregister a specific smart event callback instead of all
        callbacks matching a given type and function pointer.

2012-01-17  Carsten Haitzler (The Rasterman)

        * Add EVAS_OBJECT_POINTER_MODE_NOGRAB_NO_REPEAT_UPDOWN pointer mode
        for some very specific behavior needed for accessibility.

2012-01-19  Cedric Bail

        * Add double buffer support to buffer engine.

2012-01-20  Sung W. Park (sung_)

        * Add Direct Rendering to Evas' window optimization for Evas_GL.  This
          optimization can be significant since it avoids and extra copy from
          an offscreen buffer.  Normally, Evas_GL will render to a render
          target using an FBO. This can be enabled by giving
          EVAS_GL_OPTIONS_DIRECT hint in the config options_bits. Direct
          rendering is actually done if the following conditions are met -
          1) All GL rendering is done in the pixel_getter callback 2) No
          rotation on the image object 3) Corresponding image
          object has alpha disabled.

2012-01-23  Tom Hacohen (TAsn)

        * Textblock: Added evas_object_textblock_style_user_push/pop.
        This is used to override the default style set for an evas object.
        For example, this can be used to nicely change the font and size
        in a text editor.

2012-02-23  Carsten Haitzler (The Rasterman)

        * Fix rouding of update regions for image objects when scaled
        (leaves trails without this).

2012-02-23  Cedric Bail

        * Remove Software SDL engine.

2012-02-23  Carsten Haitzler (The Rasterman)

        * Add evas_object_ref_get() to be able to tell if others ref
        an object.

2012-04-03  Gustavo Sverzut Barbieri (k-s)

        * Box layouts: fix handling of weights that have decimal parts,
        they were being handled as "int" where "double" was expected.

2012-04-12  Carsten Haitzler (The Rasterman)

        * Fix gl engine clipping bug when rendering to evas map fbo's
        when gl window buffer is smaller than the fbo. used wrong
        surface size in clipping logic.

2012-04-12  Tom Hacohen (TAsn)

        * Textblock: Fixed compilation with liblinebreak disabled.

2012-04-14  Carsten Haitzler (The Rasterman)

        * Fix color multiplier staying set when rendering map.

2012-04-22  Carsten Haitzler (The Rasterman)

        * Fix shader binary saving to save with dir existing already.

2012-04-26  Carsten Haitzler (The Rasterman)

        1.2.0 release

2012-04-26  Cedric Bail

        * Lock less font rendering.
        * Removing EVAS_FRAME_QUEUING, EVAS_SLI, METRIC_CACHE and WORD_CACHE.

2012-04-29  Tom Hacohen (TAsn)

        * Textblock: Fixed a couple of bugs with range delete.

2012-04-30  Jérôme Pinot

        * Add missing files in the tarballs.

2012-05-01  Cedric Bail

        * Compute limited bounding box for Smart object.
        * Use bounding box to reduce the number of object explored during event propagation.

2012-05-03  Iván Briano (Sachiel)

        * Add CServe2 and image cache2 that makes use of it. Several changes
        in the buffer and software engines to use the right cache if CServe2
        is requested for the application.

2012-05-14  Carsten Haitzler (The Rasterman)

        * Fix pixman rendering support if you set alpha flag AFTER
        setting image size for custom image data.

2012-05-14  Sanghee Park

        * Add Multisample Anti-Anliased surface format for Evas GL.
        The formats are divided into High, Med, Low, None, where High represent
        max number of samples.  Currently, this feature is only supported in GLES2
        environment with GL_IMG_multisampled_render_to_texture extension supported.

2012-05-16  Vincent Torri

        * Use Esvg for svg rendering. If not found, librsvg is still used.

2012-05-18  Cedric Bail

        * Remove librsvg svg loader as it is a massive source of crash in e17. If
        you still want to use it, use the evas_generic_loader librsvg binary.

2012-05-18  ChunEon Park (Hermet)

        * Update mapped objects rendering when their color is changed

2012-05-24  Carsten Haitzler (The Rasterman)

        * Fix evas_object_image_memfile_set() on non-linux systems.

2012-05-29  Tom Hacohen (TAsn)

        * Text: Fixed an issue with text object sizing.
        * Font: Fixed run-time italic.

2012-05-30  ChunEon Park (Hermet)

        * Fixed to clean up when map actually changed. Now rendering updates will be
        correct after evas_map acutally disabled/enabled for the smart object.

2012-05-30  Cedric Bail

        * Don't wake up prepare thread if there is nothing to prepare.

2012-05-30  Daniel Zaoui

        * Fix evas_free callback deletion to not sometimes abort evas freeing
        in some situations, thus leaking.

2012-06-10  Carsten Haitzler (The Rasterman)

        * Fix evas font handling so bitmap fonts work again like they
        once did. This ifxes max height, and max ascent/descent
        calculation for 0 em fonts with 0 bbox size (bitmap case), and
        fixes 1 rounding error in text objects that placed ascent in the wrong
        place by 1 pixel for even ascents.

2012-06-10  Cedric Bail

        * Limit the updated region to fit in CPU cache for Pipe rendering.

2012-06-12  ChunEon Park (Hermet)

        * Fixed simple line drawing on s/w backened. Unmatched loop scope caused the
        destination buffer pointer march in place.

2012-06-12  ChunEon Park (Hermet)

        * Removed empty evas_object_map_source_set/get APIs. Will Not be implemented.

2012-06-13  Mike Blumenkrantz

        * Fix crash in evas_object_image_add() when called prior to setting an engine
          for the given canvas.

2012-06-14  Cedric Bail

        * Cache convertion from Evas_Map to RGBA_Map.

2012-06-15  Vincent Torri

        * Add Textgrid object.

2012-06-15  Mike Blumenkrantz

        * evas_object_smart_members_get() now returns NULL on non-smart objects

2012-04-26  Carsten Haitzler (The Rasterman)

        * Fix GL engine bitmap font handling

2012-06-19  Vincent Torri

        * Remove uselesss software DirectDraw 16 bits engine

2012-06-27  Sung W. Park (sung_)

        * Added (w, h) <= 0 check in EvasGL surface that was never handled before.
        * Handled evas_gl_make_current to return error when either surface 
        or context is NULL.  Before, when that was the case, it just did 
        make_current(NULL, NULL) internally. 

2012-04-28  Carsten Haitzler (The Rasterman)

        * Fix font instance refcounting for textprops that hang around.

2012-06-29  Jiyoun Park

        * upstream merge
        * Merge remote-tracking branch 'remotes/origin/upstream'

2012-07-03  Christopher Michael

        * Merge Tizen changes to upstream EFL.
        * Support gif scaling in evas gif loader.
        * Create vertex & fragment shader(s) in the gl_common engine.
        * Don't call glGetTexLevelParameteriv unless it is supported.
        * Support evas_cserve2 in the wayland_shm engine.
        * When freeing a gl_x11 window, make sure to call eglMakeCurrent with a null surface
                to inform EGL that this window is no longer valid.

2012-07-04  Cedric Bail

        * Make pipeline rendering use more extensively the prepare stage.

2012-07-04  Gustavo Lima Chaves

        * Add simple interfaces support to Evas smart classes

2012-07-05  ChunEon Park(Hermet)

        * Fixed Map pipe region issue. It caused the incorrect object rendering order
        on gl backened.

2012-07-05  Cedric Bail

        * Strongly disable Evas pipe rendering.

2012-07-05  Cedric Bail

        * Don't let bad map sneek at render time and ban them as early as possible.

2012-07-07  ChunEon Park(Hermet)

        * Let Draw Text with viewport size instead of window size. When map is enabled then it should be rendered completely.

2012-07-11  Tom Hacohen (TAsn)

        * Fixed runtime emboldenment with bitmap fonts.

2012-07-16  Hermet (ChunEon Park)

        * Fixed to do pre render for the children of mapped object.

2012-07-17  Cedric Bail

        * Fix garbage left by mapped smart object when they fly away from the canvas.
        * Fix map life cycle.

2012-07-18  Carsten Haitzler (The Rasterman)

        * Fix evas box to not skip dealing with size hint changes
          while it lays out objects. This breaks elementary badly and it should
          never have done this. This broke the general logic of size
          hint handling.

2012-07-19  Jiyoun Park(jypark)

        * Fix jpeg save bug related with error handler

2012-07-22  Cedric Bail

        * Don't crash when calling evas_object_smart_type_check without type.

2012-07-24  Ingvaldur Sigurjonsson

        * Fix typoe in docs

2012-07-24  Hermet (ChunEon Park)

        * Fixed evas_gl resource list have cleared properly when it is released
        so it would be no problem when it is reinitialized in one same process.

2012-07-24  Cedric Bail

        * Handle Proxy with the right context.

2012-07-24  Carsten Haitzler (The Rasterman)

        * Fix long-standing bug when changing layer of a smart object,
        its children dont change their layer value and pointer with it, thus
        getting layer from them get you the wrong one.

2012-07-26  Cedric Bail

        * Keep track of inactive proxied object change so we always update the proxy correctly.

2012-08-01  Jiyoun Park(jypark)

        * Fix gif load bug. we initialize first frame buffer of gif loader
