With Wayland around the corner, a lot of toolkits are adding client-side
decorations support with undecorated ARGB32 windows. One of the big issues
with this is that if you want to implement shadows or invisible borders for
resizing frames, you end up with window managers not understanding where
the frame extents actually are, since they just measure the X window.

In GTK+, I have a local patch that adds a _GTK_FRAME_EXTENTS property,
similar to _NET_WM_FRAME_EXTENTS, which describes additional padding or
spacing around the frame of the window, meant for decorations like
invisible borders or shadows.

The only thing I can't think of is a name for it. _NET_FRAME_EXTENTS was my
idea, but it's very likely to be confused with _NET_WM_FRAME_EXTENTS.
