gdkWindowShapeCombineMask
Applies a shape mask to window. Pixels in window corresponding to
set bits in the mask will be visible; pixels in window
corresponding to unset bits in the mask will be transparent. This
gives a non-rectangular window.

offset.y) |

If mask is NULL, the shape mask will be unset, and the x/y
parameters are not used.
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.
