- - Rename "SSE" to "MMX_EXTENSIONS"
-
- - Behdad's MMX issue - see list
+ - Testing
+ - Test implementations against each other
+ - Test both with and without the operator strength reduction.
+ They shold be identical.
- SSE 2 issues:
- - Commented-out uses of fbCompositeCopyAreasse2()
-
- Use MM_HINT_NTA instead of MM_HINT_T0
- Use of fbCompositeOver_x888x8x8888sse2()
- - Use pixmanFillsse2 and pixmanBltsse2
-
- Update the RLEASING file
- Things to keep in mind if breaking ABI:
the required precision by simply adding offset_x/y to the
relevant rendering API?
+ - Get rid of workaround for X server bug.
+
- pixman_image_set_indexed() should copy its argument, and X
should be ported over to use a pixman_image as the
representation of a Picture, rather than creating one on each
(They only exist because they are theoretically available to
drivers).
- - Regions should become 32 bit
+ - 16 bit regions should be deleted
- There should only be one trap rasterization API.
to indicate the actual depth. That way PIXMAN_x4c4 and PIXMAN_c8
won't collide.
+ - Maybe bite the bullet and make configure.ac generate a pixman-types.h
+ file that can be included from pixman.h to avoid the #ifdef magic
+ in pixman.h
+
- Make pixman_region_point_in() survive a NULL box, then fix up
pixman-compose.c
- Possibly look into inlining the fetch functions
+ - There is a bug with source clipping demonstrated by clip-test in the
+ test directory. If we interprete source clipping as given in
+ destination coordinates, which is probably the only sane choice,
+ then the result should have two red bars down the sides.

- Test suite
- Add a general way of dealing with architecture specific
this, I suggest just using 32-bit datatypes by setting
IC_SHIFT to 5 for all machines.
- - Consider whether calling regions region16 is really such a great
- idea. Vlad wants 32 bit regions for Cairo. This will break X server
- ABI, but should otherwise be mostly harmless, though a
- pixman_region_get_boxes16() may be useful.
-
- Consider optimizing the 8/16 bit solid fills in pixman-util.c by
storing more than one value at a time.
What about color spaces such a linear vs. srGB etc.?

done:
+- Use pixmanFillsse2 and pixmanBltsse2
+
+- Be consistent about calling sse2 sse2
+
+- Rename "SSE" to "MMX_EXTENSIONS". (Deleted mmx extensions).
+
+- Commented-out uses of fbCompositeCopyAreasse2()

- SSE2 issues:
- Crashes in Mozilla because of unaligned stack. Possible fixes
- Make use of gcc 4.2 feature to align the stack
