Workaround

Thanks for the trace. The driver doesn't report the ARB_shader_texture_lod
OpenGL extension, so we disable shader model 3 support. You're right that your
graphic card should support it, but the GL driver doesn't claim it so, since my
patches you've mentioned, we're reporting that as unsupported to the
application.

The attached patch checks also for a different extension flag (which still
pretty much implies SM3 support but for ARB shaders instead of GLSL shaders),
it should give you back the behavior you had before my patch series, I think.

BTW, in your trace I see texture uploading/downloading errors which don't look
good, but they should be unrelated to my patches. I guess let's see what
happens with my patch in place...
