Yuri Benditovich da0680c8d5 qxl-wddm-dod: Enable hardware pointer acceleration 
Windows disables hw pointer acceleration and draws the cursor
in frame buffer if the driver does not report pointer capabilities
in QueryAdapterInfo. In this mode OS usually does not send pointer
commands to the driver or does it with pointer set to invisible
state. This mode of operation consumes CPU time and device-to-host
traffic. Now we enable pointer hardware acceleration.
