This consists of tests adapted from Khronos conformance suite and
Android surface flinger. While the former deals with getters/setters,
enumrations and simple sampling of texture based images, the latter
addresses bilinear sampling of non-GPU written subsampled UV-planes
and conversion from YUV to RGB.
The original Android test consist of two YV12 formatted textures,
one of size 64x64 and another of size 64x66. Both represent checker
board pattern each YUV component having value 63 or 191. Here I have
only the first but I'm planning to adopt the latter also if the approach
I have taken is reasonable. Instead of filling in the entire pattern I
have only written those YUV-components that are actually checked (a
dozen odd pixels) while the rest are initialised to zero. In addition
I used calculated floating point values instead of the hardcoded found
in the original. There, however, I ended up in deviations and I would
appreciate if people understanding the domain of YUV to RGB conversion
better could take a good look.
In the implementation that I have written for mesa/i965 I have also
support for NV12 format. Whereas YV12 (YVU420) has separate U- and
V-planes, NV12 has them combined into one. Hence I would like to have
the same tests for NV12 as for YV12 if acceptable.
The tests are written only for ES2 contexts, I haven't looked into
how I would separate the tests not dealing with external sampler
(samplerExternalOES is only defined for ES 2.x).
