1.) save a rendered image ..

look at the demo morph3d.java
	- uses an TGATextureGrabber -> TextureGrabber,
	- which grabs the pixels with the given spec. buffer name
	- and save's them into a file, e.g.: tga format

well, it would be cool, if you can make another derivation
of gl4java.util.textures.TextureGrabber, e.g. PNGTextureGrabber !!

you can, of course use this with on- and offscreen rendering

2.) using offscreen rendering ..

have a look at gl4java.swing.GLJPanel::paintComponent(..):
	usage of: GLContext.createOffScreenCtx

that's it ..

cheers, sven
