Recognize cards that expose GLSL 1.30 as DX10 capable even if they don't support EXT_GPU_SHADER4

You're right, I mixed up 1.30 and 1.50 there. I probably should have
actually checked before writing a reply. (We'll probably end up using
1.50 for e.g. geometry shaders on Mesa, but that aside.) Checking for
ARB_shader_texture_lod as well is redundant in that case though.

Sure, checking the GLSL version is fine.

Sure. The number of applications that really cares about the name of
the card returned etc. should be fairly limited though, and I'm a bit
surprised that World of Warcraft does. Are you sure the issue is
really with the reported card, as opposed to e.g. the amount of video
memory associated with it? CARD_AMD_RADEON_9500 has 64MB, which really
isn't a lot by today's standards.
