RRPointerToNearestCrtc is suppose to snap to the nearest Crtc,
but best_x and best_y is always positive, hence when calling
SetCursorPosition it will make the cursor even further away.
Correct delta x/y to allow negative values and also use
"width/height -1" in the calculation. Also choose the closest
Crtc by setting the "best" value.
