[Mesa-dev] [PATCH] mesa: fix GL_COLOR_SUM enum for drivers without ARB_vertex_program

[Ilia Mirkin]

Commit c13970808 (mesa: GL_EXT_secondary_color is not optional) changed

CHECK_EXTENSION2(EXT_secondary_color, ARB_vetex_program, cap)

to

CHECK_EXTENSION(ARB_vertex_program, cap)

However CHECK_EXTENSION2 checks that either extension is available, not
both. Remove the extension check entirely since the intent was for it to
always be enabled.

Someone mentioned that nouveau (dri) was getting errors with
glDisable(GL_COLOR_SUM), even though the driver should have had support for
it.
