Subject: [PATCH]pixmap: fix reverse optimus support with multiple heads
Patch-mainline: Upstream/xorg-server-1.16.99.901
Git-commit: da4bad620a6f1a58978f5279fda74da3c1c1d443
Git-repo: git://anongit.freedesktop.org/git/xorg/xserver
References: bsc#936452
Signed-off-by: Egbert Eich <eich@suse.com>

For doing reverese optimus to multiple outputs on a secondary GPU
the GPU can store the blits into a large screen pixmap, unfortunately
this means we need a destination offset into the dirty code, so
add a new API that just adds this interface.
