How do you bind a non-t_pd to a symbol ? (or else, gemstate could become a 
t_pd... just like t_outconnect is now a t_gobj in a certain branch of pd)

What would you suggest for the case of a certain other video plugin in 
which any number of fake-A_POINTERs are being used at once, instead of 
just one? I'm talking about GridFlow.

Another solution is to go back to using A_FLOAT as I was doing before. I 
dropped using a pair A_FLOAT when I implemented 64-bit support. If I go 
back to A_FLOAT it will be using 3 A_FLOAT.

BTW I just had a look at PDP again, and PDP doesn't use A_POINTER. It 
seems to be numbering all buffers using small integers, and passing those 
around as a single A_FLOAT. That's also the solution implemented by the 
little-known MAPOD video plugin. That could be an option for GridFlow.
