Do not lose window grab when approaching the edge of the screen
Currently when a freeform window is being dragged and the pointer gets
too close to the screen (stack) edge, the dragging completes. This was
done in ag/770762 to to prevent a freeform window from being dragged
fully under a docked stack.
This CL provides a different solution to this problem: while dragging a window
make sure that a big enough portion of its caption bar is still visible.
