/* The insets were literally hardcoded in the MWindowPeer.
But they are dependent upon both the window manager (WM)
and the hardware display. So, these are usually wrong.
This leads to problems with shell positioning and size.
Furthermore, there is not a published interface or way
to obtain from any given window manager the dimensions
of its decoration windows (i.e., borders and title bar).
So, given this problem in design, we must workaround.
N.B. (0) This works. But there is one functional caveat:
the frame.insets() function will usually return
the wrong values until AFTER the frame is shown.
It always did this before; it's just that now,
the values will become correct after rendering,
whereas before the values were never corrected.
(I believe this unavoidable given this design.)
(1) Note that we must/have to do this exactly once.
(2) The hardcoded values of ...create() (25,5)
are also utilized here and must be consistent.
This of course could be reworked as desired.
(3) Assume top border (title bar) is one width,
and other three borders are another width.
