Sounds good to me!
Just to be sure, you will also try to make the new table symmetric,
right? See https://github.com/pure-data/pure-data/pull/106/files.

Sorry for the repeated e-mails... here's wat I now thing I should do:
- remove cos_table and COSTABLESIZE from m_pd.h
- if "compatibility" is <= 0.54, make the cosine table 512-point,
otherwise 2048-point
I don't see any performance hit on any architecture although I think
very old machines will be slowed down by the new table size - but then
setting back compatiblity is at least a workaround.
Anyway, since we're about to see changes in Pd's audio output because
of differences between MAC ARM and even other ARM implementations (I
found that RPI 3 acted exactly like INTEL and differently from MAC M2)
I think we're going to now see different outputs on different
machines, hopefully usually small ones. So there's no more reason for
me to hold on to the old table size at all.
Any objections before I pull the switch?
cheers

Are there any existing externals that do use cos_table? When in
doubt, we could keep the old cos_table around, but deprecate it.
In the future we can remove the cos_table symbol, so old externals
simply won't load.
Cyclone used to have it, but we removed long ago when updating
[cycle~]. Old versions still have it of course and 'nilwind' (which
is basically an old version of Cyclone) still has it
