You may hit the limit on the width of the font strike first...I believe it
is 32K, but I don't remember if that's bytes or pixels.

In 5.0.x the Font Manager assumes font files are smaller than 64K; this is
a limitation rather than a bug.

Once you have a >64K font in memory and have told the Font Manager about
it, be careful.  The 5.0.x Font Manager will hang or crash trying to
re-scale a font with an owTLoc value of $xx8000 to $xxFFFF.  Yes, *this*
is a bug.  As long as your using the exact point size you have available,
there's no problem, since the FM won't have to do scaling.  Otherwise,
be careful.
