Subject: [PATCH] wmaker: improve the behaviour of window resizing by user

The original behaviour was a bit frustrating because it used the first
small mouse move to deduce the user's wished direction, but that is a bit
imprecise.

This patch divides the window in 9 rectangles:
 - 4 for corners, used for diagonal resizing
 - 4 for middles of sides, for resizing Up, Down, Left and Right
 - 1 useless in the middle of the the window, which falls back on diagonal
resizing
This leads to a more predictive behaviour.
