Filter addons can use a GetScreenRegion() but not the Device addons...
You can probably just use BScreen::Frame() .Width() and .Height()

Or just instead overrides the mouse moves from the mouse addon with the 
absolute coordinates.

I suppose so.
This design seems quite stupid from vmware... oh well.
