[mjmartin] 41166: - MouseThreadMain: Send IOCTL_MOUSE_QUERY_ATTRIBUTES to mouse driver. MSDN reads that this IOCTL is sent from the subsystem. Filter drivers can depend on this behavior. (VirtualBox guest addition drivers) Does the subsystem need the returned mouse attributes for anything? - ProcessMouseInputData: Handle flag MOUSE_MOVE_ABSOLUTE and change absolute mouse position to screen coordinates. Fixes VirtualBox mouse integration.

- MouseThreadMain: Send IOCTL_MOUSE_QUERY_ATTRIBUTES to mouse driver. MSDN reads that this
IOCTL is sent from the subsystem. Filter drivers can depend on this behavior. (VirtualBox
guest addition drivers)
Does the subsystem need the returned mouse attributes for anything?
- ProcessMouseInputData: Handle flag MOUSE_MOVE_ABSOLUTE and change absolute mouse
position to screen coordinates.
Fixes VirtualBox mouse integration.
