WindowServer+LibGUI: Shrink window edge resize hot-spots

Browse source 
The hot-spots for resizing a window by dragging its corner are now
limited to a small area around the actual corner instead of an area with
1/3rd the length or width of the window.

The hot-spots to resize a window while holding a modifier key and the
right mouse button are unchanged.
