Filtering out the non-vmware mouse moved events in an additional filter
does sound like a clean solution to me. The input_server is being made
aware of resolution changes AFAIR, maybe it could be extended to forward
this info to add-ons, but perhaps there is already a mechanism existing. I
seem to have a faint recollection of that.
