Well, you *can* use the host cursor, but by default you should not
(ie you still need to hide the host cursor and rely on the guest displaying
its own pointer). You should also honour command line -show-cursor
which overrides this to say "don't hide host cursor". Our SDL and Cocoa
UIs get this right, GTK doesn't currently.
