Here's a simple demo patch that shows how to set up the to_texture
message to perform feedback processing with a gl context. I've included
2 textures, one for using fullscreen mode, and then the other for using
the 640 480 window. This technique of switching textures allows for
resizing the jit.window without getting those error messages. With a
little ingenuity, you can be kicking out some swirly 3-D psychedelic
visuals in no time.
Have fun, and Happy Patching!
