My application was failing because we were creating floating
point textures. We would get an INVALID_VALUE by specifying a
ARB_texture_float internal format for glTexImage2D.
The attached two-line diff enables the extension, and my app gets by
the Mesa check that was failing (dunno about farther; need to run). It
seems like the extension is implemented but disabled for some reason,
though I'm basing that on a cursory look through the code and could be
wrong.
I haven't tried ATI_texture_float yet, but I'm worried that I don't see
it in `extensions.c'.
Could anyone comment on any issue[s] with ARB_float_texture in Mesa?
Thanks,
