right, this should work.
i was thinking of addint a "bang" message to the GEMgl...objects to call 
the render-routine to make them more general and not depending on the 
GemState (which most of them do not need at all, and the ones that would 
need it, do not recognize it :-()

actually it used to be that complex.
however, since gem-0.87 (i think) i have stopped this, since the 
overhead we get from using pd's message-system for the rendering is not 
that big (performance loss is "only" about 50% when using GEMgl...stuff, 
but decreases with more complex objects).

i have no real plans to change this, as it makes things more complicated 
than they should be.

right.
i am really glad about all that stuff.
tom, i have added you to the developers at pd-gem.sf.net (if you don't mind)

looking forward to the convention to see (most of) you in real-life very 
much.
