\note Under X11, it's not possible to compute decorated_h() - h()
to obtain the height of the titlebar <b> during a resize operation</b>.
That computation is to best done when the window is first mapped.
\note Under X11, FLTK is able to compute the size of window titlebars and borders
only if these decoration elements are strictly X11-based. When that's not the case,
decorated_h() returns the same value as h() and decorated_w() as w(), and FLTK
cannot access window decorations.
\note Under X11 again, the values returned by decorated_h() and decorated_w()
may not be reliable <b> during a resize operation</b>. The size of decoration elements
of a window is best computed when the window is first mapped.
