double, floats or fixed point.  Transformed and/or accelerated input generates
sub-pixel positions.  24.8 fixed point could work.  Need to think about the
range of coordinates we need.  Different from X problem, since we don't have
sub-windows, which is where X hits the 16 bit limitations.  Monitor and window
sizes haven't yet out-grown the 16 bit range.
