Evas filters: Implement advanced text effects
Add a new module in Evas to implement text effects.
The basic idea is to create some buffers (alpha/rgba),
draw some text into them, and apply various filters in a
sequential way.
A small script language allows you to set a filter to a
text object. This can then be passed through an Eo API
or using Edje directly (under the field description.text.filter).
Right now, the software engine should work fine, but GL rendering
suffers from a few limitations (no scaling and no proxy rendering,
which means a few effects might not work well).
More documentation will follow, and examples as well.
But, please bear in mind: this is a HIGHLY EXPERIMENTAL feature.
I'm including it to EFL 1.9 so that people can play with it,
but it should not be considered stable at this point in time.

a mask on top of input and output buffers.
So, basically they blend input+mask into a third buffer output.
If output is RGBA then mask or input MUST be RGBA.

Evas filters: Implement blend functions
Currently, blending supports the following:
- Alpha --> Alpha (simple alpha masking)
- Alpha + Color --> RGBA (same as mask)
- RGBA --> RGBA (normal blend)
- RGBA --> Alpha (desaturate using A=(R+G+B)/3)

Evas filters: Import main implementation file
evas_filter.c contains the entry points for the evas filters subsystem,
in particular, the filter API, the (yet very basic) buffer management
system, the command queue and main context handling functions.
Right now, the Evas engine is left untouched, so these implementations
will work ONLY in the software engine.
NOTE: This will not compile on its own (thus, not added to Makefile.am),
as it will require the filter implementations to be linked.

Evas fonts: Pass RGBA_Image instead of DATA32 buffer
Since we want to be able to draw to alpha buffers, it's
easier if we pass the whole image struct instead of just
the data pointer.

Evas: Add support for Alpha buffers
Evas is an RGBA only engine, BUT we also use some alpha masks,
especially in the font rendering pipeline.
This commit adds basic support for alpha buffer operations
(blend and copy).
RGBA_Image can then point to either alpha-only data, if
its colorspace is grey.
