[PD-dev] [GEM] cvs commits

hiya,

...like the subject says:

- several new geos:
	ripple: x/y center-able ripple distortion
	rubber: grab the image & stretch
	slideSquares: image revealed via sliding squares
	newWave:  updated, added some controls

- pix_texture2 changed to float gl commands
- rectangle:  added chris' glBlend code

...speaking of which, it'd be really nice if some nonMac platform 
could try this glBlending, cuz it could easily be added to all 
geo's...but we don't want to go overboard w/o confirmation...

l8r,
jamie
