If it's not posible to calculate a title bar*s height in GNU/Linux,
due to the different windows managers, why don't CREATE YOUR OWN
TITLE BAR WITH YOUR OWN HEIGHT ?
What about creating a window *without* a title bar first, then adding a
title bar to it and interpret the height difference
Can you explain why you need the complete height ?
Well you may want to position a window relative to other windows, for
example - like a playlist window that is part of a media player but can
be positioned seperately. Or you may want to center a window on the
screen ...
