[PD] New feature for pix_buffer

[Florian Grond]

Dear List,

I recently started programming my own GEM externals. Since I use windoze 
I don't know what all the features of the other externals available for 
OSX and Linux are.
We have added to the pix_buffer object the feature that the buffer can 
be used as a cyclic buffer, sending the message cyclic 1/0. Like this it 
would be easily possible to track the last x frames from a movie or a 
cam. If anybody would be interested in this feature I would be happy to 
pass on the sources, yet I don't know how to integrate it to any CVS etc.

In case this feature is needed just write me,

Florian
