Hello, the LWJGL-based renderer was not included in the final 2.0 release because it needs to be updated to make it work with the core classes (PGL, PGraphicsOpenGL, etc), which went through some refactoring and cleanup in preparation for 2.0 final. It was fairly functional at around 2.0b8, but I didn't test the LWJGL's applet launcher at the time. Any help with the update work will be greatly appreciated!
