This seems complicated. Normally, pointer motion only effects
one screen at a time and there are probably some complications with
making it behave otherwise. Also, unless the virtual desktop
sizes and viewport sizes of the individual screens were restricted
the effect would be lost. Consider what happens if someone did
a mode change on one of the monitors? What happens to the panning
behavior then? At the moment there are no special viewport considerations
for Xinerama. Xinerama, from the point of view of the DDX is just
like any other multihead mode, so what you are suggesting is actually
a large departure from the current architecture.
