PIGLIT: {'result': 'fail' }
570ed2be7d776211e1ca2a7a4c44ee6a1d141714 is the first bad commit
commit 570ed2be7d776211e1ca2a7a4c44ee6a1d141714

ReadPixels: Force ALPHA to 1 while rebasing RGBA values for GL_RGB format
When performing a ReadPixels operation, we may be reading from a buffer
that
stores alpha values, but that is actually representing a buffer with no
alpha
channel. In this case, while rebasing the values, touch up all alpha values
read to 1.0.
This commit fixes the following piglit (sub) tests:
ARB_texture_float/fbo-colormask-formats
GL_RBG16F_ARB
EXT_texture_snorm/fbo-colormask-formats
GL_RGB16_SNORM
GL_RGB8_SNORM
GL_RGB_SNORM
It likely improves the results of other tests as well, but a PASS remains
elusive due to additional bugs.
