I think a core commenting sprint would be *very* helpful, specially to those of us (me) who would like help in understanding the black magic inside.

That is an important question. Pd code is full of clever tricks and
bit hacks for dsp efficiency. What is the origin of q8_rsqrt(), why
and how does it work? What about PD_BIGORSMALL() in m_pd.h? And the
mysterious UNITBIT32 number in d_osc.c? Ideally such code should be
commented not only to denote its function (if necessary) but also to
reference the origin so you may be able to find info.
