To write an LDEF that uses multiple fonts,
1.) you can have your LDEF's draw routine save the GrafPort's current font,
draw the text in the new font, and restore the font. Since this requires
all the fonts you use to be in memory, this takes a lot of RAM, and a lot
of time for the initial disk reads.
2.) You can use bitmaps. See the tech note on drawing SICNs for tips on
drawing arbitrary offscreen bitmaps.

Both of the above techniques have one problem: the List manager does not
support variable sized items. 12 point Geneva is not the same height as 14
point Symbol. What I did was: I wrote a menu definition procedure, an MDEF,
that handled variable sized, scrollable units. Then I wrote a package to
simulate a list manager list to the user, but it was actually calling my
MDEF to do the drawing.
