[Graphical] Border issue moving a window out of tiling

[STiAT]

Hi,

if you have a tiled window which had a certain size before, if you move it out of tiling the border is in the window in the size of the tiled window, not the size of the window you're moving, and it's not as if the rectangle stays where the tiled window was, it moves with the window you're moving (in the size the tile has been):

Not really a hard issue, just looks bad in my opinion.

Reproduce:

• Size a window to any size
• Tile the window (I use the meta+direction keys)
• Drag&Draop the window out of tiling.
