I totally forget the details of how it's supposed to work, but the compiler
looks at the embedfonts flag when deciding whether to bake fonts into the
app. So it
is quite possible nothing in the runtime looks at that flag.

LzCanvas.maxtextheight
> LzCanvas.maxtextwidth



Those last two are obsolete, they were needed as hints to the compiler
because of
Flash 5 limitations on how runtime text could be dimensioned.
