ll in a argb_t, while the 8-bits path
will fill a 32-bits ARGB value. This also requires writing a floating
point bilinear interpolator. With this change pixman can use the full
floating point precision internally in all paths.

The high precision gradient path was falling back to the 8-bit path,
then expanding it to float. This removed any advantage of the high
precision path, so make sure our gradients are computed as floats
by adding a separate path.

Hey,
To get the floating point support in hands of users, I want to make a pixman
release. Since pixman appears to be in a bit of a limbo, is there anyone
still being a maintainer, or should I simply make a release according to the
guidelines at RELEASING?

- Define 32bpc as PIXMAN_FORMAT_PACKED_C32
- Rename pixman accessors from rgb*_float_float to rgb*f_float
Changes since v4:
- Create a new PIXMAN_FORMAT_BYTE for fitting up to 64 bits per component.
(based on Siarhei Siamashka's suggestion)
- Use new format type PIXMAN_TYPE_RGBA_FLOAT

New version, with better checks to pixel accessors and alignment. Also
some small tweaks, and making stress-test work with the changes.
Hopefully we can move forward and finalize the bitstream format, so
we can start exposing it in pixman.
Maarten Lankhorst (2):
pixman: Add support for argb
or to F16.
Changes since v1:
- Use RGBA 128 bits and RGB 96 bits memory layouts, to better match the opengl
format.
Changes since v2:
- Add asserts in accessor and for strides to force alignment.
- Move test changes to their own commit.
