[PD] GEM GEMglClearColor alpha ?

[vade]

Hello

Playing with the gl objects in GEM (0.90) on OS X (Pd 0.38-4  
Extended, via Hans) , ive noticed that GEMglClearColor has 5 inputs,  
one for the gem render chain, 2 - r, 3 - g, 4 - b and presumably 5 -  
alpha, yet, changing alpha results in no change in the window  
Changing the RGB values does, just like [color] to gemwin (as it  
should).

Presumably, changing the alpha would act to let the scene draw 'over'  
itself, and give an easy way to do trails/blurring. Jitter supports  
this feature (not griping.. just saying :), any chance , or  
workaround to get similar functionality, as I love the aesthetic of  
it. Id rather not use snap2pix/snap2tex.

Thanks,
