[PD] Gem initial states and help patches

[Peter P.]

Hi list,

I would like to suggest that the help patch for [pix_gray] mentions the
object's default state (off). Especially as it's different from
[alpha]'s default state.
It would be cool if [pix_gray] had an argument initializing its state.

Furthermore it seems that opening the help patch for [pix_pix2sig~]
opens the patch for pix_sig2pix~.
The help patch for [pix_sig2pix~] itself is opened correctly.

cheersio,
P
