[PD] Gem, arguments to particle domains.

Hi, all.

Below is an excerpt from the help file to [part_source] I found in the
latest Pd-extended (stable), describing the arguments understood by the

--- From here ---

<domain>: one of "point", "line", "triangle", "plane", "box", "sphere",
"cylinder", "cone", "blob", "disc", "rectangle"

<arguments>: up to 9 floats, defining the specified domain (like "x y z"
for "point", "x1 y1 z1 x2 y2 z2" for "line", "x y z r" for "sphere",
...). The meaning of the arguments depends -of course- on the domain.

--- Up to here ---

As far as I know, there is a lot left unexplained in this particular
help file attached to Pd, especially on how many arguments each domain
likes to eat and what the floats represent.

Embracingly, I did not know till a few days ago that there is another
API which is the mother of Gems's particle handler and that the
arguments are explained in its documents. For example, I've just learned
this morning that "sphere" takes 4 arguments and their purpose seem to
correspond to what is said in the API manual.

Am I just going through unnecessary trouble because of me not knowing of
a manual pakced with Gem, or shall I be taking notes of my discoveries
so that I can perhaps commit to the help file?
