Note that AMD_texture_texture4 is only defined for single-component
textures (not even RED allowed due to the age of the ext -- only ALPHA
/ LUMINANCE / DEPTH_COMPONENT / INTENSITY) -- but it doesn't say what
will happen when a "bad" texture is supplied. I guess it's reasonable
to take the ARB_texture_gather interpretation as if the driver
reported MAX_PROGRAM_TEXTURE_GATHER_COMPONENTS_ARB == 1, i.e. it's the
user's fault if something doesn't work.
