Window.shapeCombineRegion

Makes pixels in window outside shape_region be transparent, so that the window may be nonrectangular. If shape_region is NULL, the shape will be unset, so the whole window will be opaque again. offset_x and offset_y are ignored if shape_region is NULL. On the X11 platform, this uses an X server extension which is widely available on most common platforms, but not available on very old X servers, and occasionally the implementation will be buggy. On servers without the shape extension, this function will do nothing. This function works on both toplevel and child windows.
