Peter Hutterer 45f447dafd dix: force a minimum of 0 for screen coordinates. ...

Currently the root coordinates may fall into ]-1..0] if the subpixel
remainder is less than 0. Screen coordinates mustn't go below 0, so use
miPointerSetPosition to cap off the remainder if the coordinates are below
0.

This is cheating a bit, a more comprehensive solution to deal with subpixels
correctly when crossing screens is needed. For now, this'll do.
