<pre>Hi All, I've created a consumer plugin which uses opengl to draw
a bunch of stuff and all is now working nicely (finally.. thanks to
all...)</pre><pre> however now I would like to send some information
to QC as well, to control branching and other stuff to happen outside of my
plugin... seeing as a consumer can't send any data to QC I'm trying to
convert it to a processor patch.. but am not having much
luck.</pre><pre> </pre><pre><span class="Apple-style-span"
