- 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)

Browse source

- ProcessMouseInputData: Handle flag MOUSE_MOVE_ABSOLUTE and change absolute mouse position to screen coordinates.
Fixes VirtualBox mouse integration.
