The remapping will work only when the driver controls
the placement of drawn pointer, i.e. when the input
device in VM is usb-mouse and the Spice Agent is not
active.

On return from S3 the driver may receive failure when
calls DxgkCbAcquirePostDisplayOwnership. In general the
driver is not expected to use this method when returns
from S3 but it is not simple to distinguish between S3
and S4 power transition (possible, due to hybrid sleep).
Current commit avoids returning error on power transition
and obtains best known default video mode info instead.

Even if initial display resolution is not available at driver start, try
to find it in the registry. Then the driver can prevent black screen
on uninstall/disable also when it was installed on UEFI machine after
the production driver 0.18 which did not report valid video mode.

Setting this flag on this command cause some performance issue.
When the server see this flag it updates the frame buffer and copy
part of it in a new allocated image. However for this command the
image is not used wasting only CPU and memory.
Also the frame buffer update causes the elimination optimisation
to be less effective causing more network usage.

Due to wrong addresses passed to class driver, it never does
unmapping of physical memory, causing a leak of virtual address range.
On x86 systems the device fails to start due to failure to
map physical memory range after 10-50 cycles of disable-enable.

Upon change of display mode the driver waits until all the
queued drawables pushed to the host or discarded. This eliminates
server warnings "rendering incorrect" in "get_drawable" when the
drawable command was created by guest driver just before change
of display mode and posted to the server during or after the change.
This patch and comments are heavily based on a patch sent by
Yuri Benditovich (with serialization code completely changed and
added generation to discard pending commands on old surface).

Previous Windows drivers use mainly DEVRAM so in some environments
