[PD] Drawing lines in gem with alpha fade

[James Dunn]

I've been sending x/y values to [curve] to draw some lines in gem and 
the only way I've been able to get them to stay rendered is to use 
single buffer mode using [buffer 1( messaged to [gemwin].

Can someone suggest a better method using double buffer perhaps? I would 
like the lines to fade out after some seconds. I looked at pix_snap2tex 
and gemframebuffer but could only get one line rendered. Is this 
possible with the particle objects?

thanks

James
