Subject: Mesa uses the glVertexAttrib*NV functions to implement fixed-function
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1b8d0f149e0afac859c4c1e1e47772bb19da0187;p=mesa.git

Mesa uses the glVertexAttrib*NV functions to implement fixed-function
attributes in display lists.  If a driver doesn't add entry points for
GL_NV_vertex_program, it will explode.  This patch adds GL_NV_vertex_program
to the list of default extensions whose entry points are added by
driInitExtensions.

Thanks go to Roland Scheidegger for tracking the problem down and suggesting
the fix.
