Well I was just trying to keep the test case simple without any logic knowing
about drm-fourcc formats and if the alpha is to be treated specially for one
and not for the other. Something on these lines:
------
Tests that one can sample the given buffer without other mipmap
levels by setting texture filtering accordingly.
v2:
- compile only on platforms that have drm (Eric)
- use standard drm definitions for fourcc instead of duplicated
local (Daniel, Eric)
- removed irrelevant quote of the spec (Eric)
- use helper variables for width, height and cpp instead
of repeating the magic numbers over and over again (Eric)
- used the same refactored common logic as the mipmap ARGB test
v3 (Eric):
- use properly linked egl-extension calls
v4 (Eric):
- add to 'all.tests'
- removed inclusion of standard EGL entrypoints as there is the
special dispatcher for the test cases to use
v5 (Eric, Chad):
- sample using image-external extension
- fix inclusion in all.tests
v6 (Chad):
- check for GL error instead of EGL when invoking
glEGLImageTargetTexture2DOES()
- allow the test to be skipped if external textures or the
chosen format are not supported
- fix the scope of the comment describing the need for closing
file descriptors in case image creation fails
- introduce format as command line argument and merge the XRGB
test here
