Take the Windows taskbar into account when deciding on the maximum

size of the puzzle window. This has involved some _completely
stupid_ window manipulation: in order to figure out in advance how
big I want my main window to be, I first have to _create_ the status
bar so I know how tall it is; but since I can't reparent it into my
main window after I've created it, I then have to throw that status
bar away and create a new one. *sigh*
