Subject: mesa: fix GL_COLOR_SUM enum for drivers without ARB_vertex_program
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=739dc95e676b31349525b7daf99453b987748248;p=mesa.git

mesa: fix GL_COLOR_SUM enum for drivers without ARB_vertex_program

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.

v2: Fix glGet*(GL_COLOR_SUM) too.  Suggested by Ian.
