Message:

Devices/Graphics, Main, FE/Qt: add plumbing for sending cursor position events.
bugref:9038: FE/Qt: better handle mouse cursor when toggling integration
The Linux and X11 graphics driver sends notification when the guest cursor
position changes. This could be used by the front-end to switch back to
pointer capturing without requiring that the guest draw the cursor, which
often results in artifacts. This change adds the necessary plumbing between
the graphics device and the user interface.
