1. Font picker dialog

Ok, here is the font picker for screen fonts. I also have a font picker
for printer fonts which will only show fonts that work for the default
printer.

In case anyone is interested I have a fairly complete printer library I
wrote last year before David got printer dialog into winlib. It has some
extra capabilities such as the ability for the coder to preprompt the
printer mode (portrait/landscape), the print from-to pages (from a print
dialog routine by Barrend Maaskant),disable the print to file button as
well as interface with the print setup dialog. It also has routines for
1Up, 2Up and 4Up printing per page, selecting of print font and more.
Again the code is not very professional or efficient but works.

Enjoy,
Judith Evans
