[PATCH qxl-wddm-dod 3/3] Remap the pointer in case of rotated screen

[Yuri Benditovich <yuri.benditovich@xxxxxxxxxx>]

https://bugzilla.redhat.com/show_bug.cgi?id=1791804
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.
