Subject: mesa, st/mesa: disable GL_ARB_geometry_shader4
X-Git-Tag: 062012170305~8344
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bb7c2691d25b6aaea2663f85a5b6723edbf56938;p=profile%2Fivi%2Fmesa.git

mesa, st/mesa: disable GL_ARB_geometry_shader4

The new GLSL compiler doesn't support geom shaders yet so disable the
GL_ARB_geometry_shader4 extension.  Undo this when geom shaders work again.

NOTE: This is a candidate for the 7.10 branch.
