Subject: r100/r200/r300/r600: Set MaxCombinedTextureImageunits.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0943706d35e3955cacbc3b690cfb1e2dfb78d639;p=profile%2Fivi%2Fmesa.git

r100/r200/r300/r600: Set MaxCombinedTextureImageunits.

Fixes glActiveTexture to set GL_INVALID_ENUM when trying
to activate texture unit that is not available.

piglit test case general/texunit passes now.
