<pre>The test failed because in
glTexImage2D(format=GL_RGBA, type=GL_UNSIGNED_SHORT_5_5_5_1)
Mesa chose BRW_SURFACE_FORMAT_R8G8B8A8_UNORM as the storage format.
The two formats have incompatible precision in the alpha channel. One
provides binary alpha; the other provides gradient alpha.
Intel hardware supports BRW_SURFACE_FORMAT_B5G5R5A1_UNORM, so we need to teach
glTexImage2D to choose that instead.</pre>
