Warp pointer on first/last pixel
Previously, the pointer would get warped when it had left the window. This doesn't work when sxiv is run in fullscreen mode (or similar -- see dwm's monocle mode): The pointer can never leave the window in such situations. To fix this, warp the pointer when it's on the first/last pixel. To avoid an endless warping loop, the new position must be at least one pixel away from the next warp position.
