Well, it appears (after some CodeView-style investigation) that the "user
units" are just twips after all, and it's quite easy to get the right size
font.  I only wish that they referred to the units as twips instead of
this ambiguous "user unit".

This also now explains something else that I had wondered about...  Way
back, when I was using Excel 2.0, when I changed from an EGA display to
a VGA display, all of a sudden my worksheet font specs started getting
saved as 8.25, 9.75 and 13.75 points; I couldn't figure out why.  But it
appears that those are the actual available sizes for Helv using the VGA
driver; Excel wasn't doing the appropriate rounding...

Sorry to waste everybody's time!
