Keith Vetter 20060622 : Here's yet another Font Chooser Dialog.
I didn't like the existing ones: A little font chooser, A small font chooser, Font selector program (Raney) and one by DKF at http://people.man.ac.uk/~zzcgudf/tcl/mwidx.html#fontdlg . What I really wanted is the native Windows ChooseFont dialog, but that's still on the wish list.
So, here's my version of the font chooser dialog which tries to emulate the native Windows dialog closely. It will use the tile package if present (and looks much better).
