Subject: [spice-gtk PATCH] Single headed monitor updates should start at 0,0

From: Sandy Stutsman <sstutsma at redhat.com>

For Windows VMs, each monitor is driven by its own instance of the qxl
driver, so monitors have only one head.  With the addition of the
monitors_config message in the Windows Driver, it is now possible to
have a single headed monitor with a non zero position.  Even so, the
update_area call should be for the whole monitor extent.
