[PD] GEM pix_rgba

[tim cleminson]

hi,
	i am experiencing problems with the pix_rgba object. it seems to shift 
the color fields around so that blue becomes red. yet this object is 
necessary precursor if you use the pix manipulator objects, what's 
going on can anyone help?.
	I have placed the pix_rgba object bellow pix_film and above 
pix_texture2 objects.
I'm using OS X 10.2.3 on 12' Powerbook with pd 0.36 and gem 0.87

thanks tim
