aye !

although i have coded it, i had a lot of problems myself, getting it to
work ;-)
in theory, it should write down a frameshot to disk, either by "bang"ing
it, or automatically each render-cycle.

anyhow, pix_write is very pre-alpha (and therefore not documented))
hopefully i will find some time to add jpeg-support and make the
controlling somehow sensible (or at least, understandable). it shouldn't
be that hard.
since the control-behaviour is VERY likey to change, i wouldn't use it
very much...

creation:
4 arguments are allowed, 2 are (still) recommended:
"pix_write 0 0 100 100" will snap a image of size 100x100pixels,
starting in the lower-left corner. if your gem-win is 256x256 pixels
large, you will capture about 1/4 (and not the whole frame, scaled down
to 100x100)
"pix_write 256 256" will capture a 256x256-pixel-sized frame, starting
at 0+0

you can change both position and size by sending pairs of floats to the
second (third) inlet.

usage:
"auto 0" will *start* writing TIFFs each rendering-cycle
"auto" will *stop* writing TIFFs
"auto <n>" should start writing compressed (level <n>) JPEGs, but is not
yet implemented

"auto mypath 0", should *start* writing TIFFS named mypath<i>, with i
counting from 0 upwards.

i do not know, whether it really works this way....
i do hope, that i will find some time soon to fix the behaviour (stop
"auto" stopping to automatically write and "auto 0" start it,...)
