fiddlerwoaroof/crawl - Change 66PPHRP2IW7VAVENBJ4KRO6MEF2HKYZHO4RWCISXC2ZXM6CK2XEAC

Made flip_rectangle() use clamp_in_bounds().

Prevented divide-by-zero error in rectangle_dimensions().

Shrunk clamping rectangle in clamp_in_bounds() one square away from each side to prevent floor squares from ever abutting the very edge of the level grid.
