Subject: [PATCH 7/7]xf86-video-sis: remove the GlxSetVisualConfigs stub and friends
Patch-mainline: Upstream
Git-repo: git://anongit.freedesktop.org/xorg/driver/xf86-video-sis
Git-commit: a50b2b3412dd8e7f3916acb142c942e85ffcb3e5
References: 
Signed-off-by: Max Staudt <mstaudt@suse.de>

The function was an empty since 2008 at least. Remove it alongside the
unused GLX visuals code.

With this all the GL/GLX dependencies in the driver are gone.
