Broken Input Shaping

["natan yellin" <aantny gmail com>]

Hello,
I've been trying to get gdk_window_set_child_input_shapes() to work without
success.

Interestingly, if I don't use an input shape and I just call
gdk_window_set_child_shapes then it works fine.

As far as I can tell, the function is totally broken. If someone can confirm
that it doesn't work for them either then I'll file a bug on bugzilla.
