Git-commit: 4fca18dc03669bada75175df289fbee41275208e
Patch-Mainline: Upstream
Author: Adam Jackson <ajax@redhat.com>
Subject: xfree86: Add IndirectGLX server flag (v2)
Signed-off-by: Michal Srb <msrb@suse.com>
References: bnc#1031887

Not all display managers make it easy (or possible) to modify the
command line flags passed to the server, so add a way to get to it from
xorg.conf.

v2: Fix the FlagOptions list to not have IGLX after the terminator (Alan
Coopersmith)
