randr/xfree86: Fix a one off error in the panning calculations.
- Example: mode 1280x1024, panned area 1281x1024 panned_area.x2 = 1281 mode.width = 1280 If you substract 1280 from 1281, then that leaves you with one. Which is the one pixel that you need to move to actually see the last pixel collumn. Substracting 1 from this will consistently prevent you from seeing the right and bottom edge.
