A strut is an area (typically along the edge of the screen) where
windows should stay away from. Usually there is something like a task
bar or menu bar or panel there. But if you maximize a window, that area
will remain unused. With some window managers you can't even move
another window over them, even partially.

The task bars are also windows, of course, and it would be usual that
those windows also set the strut. But in theory it could be a totally
different window which does it.

Here is a page describing it:
https://specifications.freedesktop.org/wm-spec/1.3/ar01s05.html
linked from
https://stackoverflow.com/questions/21384819/x11-struts-geometry

ctwm treats _NET_WM_STRUT_PARTIAL like _NET_WM_STRUT, so the extra
fields (which reduce the reserved area) are ignored.
