mesa: GL_TEXTURE_BORDER_COLOR exists in OpenGL 1.0, so don't depend on GL_ARB_texture_border_clamp
On NV20 (and probably also on earlier NV GPUs that lack GL_ARB_texture_border_clamp) fixes the following piglit tests: gl-1.0-beginend-coverage gltexparameter[if]{v,} push-pop-texture-state texwrap 1d texwrap 1d proj texwrap 2d proj texwrap formats All told, 49 more tests pass on NV20 (10de:0201). No changes on Intel CI run or RV250 (1002:4c66). Signed-off-by:Ian Romanick <ian.d.romanick@intel.com> Reviewed-by:
