Subject: Bump GL_MAX_TEXTURE_COORDS from 2 to 4
X-Git-Tag: 062012170305~10660^2~625^2~203
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cfb3536f10dac343ad635be7f979b292c97eb1a3;p=profile%2Fivi%2Fmesa.git

Bump GL_MAX_TEXTURE_COORDS from 2 to 4

Every platform that supports GLSL sets GL_MAX_TEXTURE_COORDS to at
least 4, so hard-code 4 for now.

This causes the following tests to pass:

    glslparsertest/glsl2/norsetto-bumptbn_sh_fp.vert
    glslparsertest/glsl2/xreal-lighting-d-omni.vert
    glslparsertest/glsl2/xreal-lighting-db-omni.vert
    glslparsertest/glsl2/xreal-lighting-dbs-omni.vert
