Re: detach() for FXFont

I only have to call detach() on Windows on either the main window or a
non-modal window. On modal windows I do not need to call detach() prevent a
leak.

=======================

It appears that FXFont::detach() behaves wrongly.  Theory: detach() removes
connection between widget and its server-resident resources.

Clearly, FXFont doesn't do this.  So its not working right.
