i still think that this is a sane plan (though it could probably be
simplified a bit more).
if there is interest, i could provide a patch to implement that.


lately i was thinking about the possibilities to allow loading/using of
externals with the "wrong" precision, e.g. a legacy mode, that would run
old (single precision) externals in a double precision runtime.

most likely it's possible as long as the external doesn't use any
heap-allocated numbers (tables), but it's probably not wort the effort.

i *guess* that max7 would allow to run single-precision DSP code (even
though by now, max uses double precision signals), but might be totally
wrong.
