[Newbies] OpenGL-Tutorial updated

I added a couple of minor bits to my ongoing implementation of the HE OpenGL tutorials. Only 2-5 are available right now.

http://croquet-src-01.oit.duke.edu:8886/Contributions' OpenGL-Tutorial-LDE.10

I added a timer option ala the OpenGL class>>example, basically.

To run, as is:

myOGLView := OGLMorphTutorial new. myOGLView openInWorld. myOGLView toggleTiming. "on" myOGLView toggleTiming. "off"

Currently it only runs Lesson 4. To change this, edit #renderScene to use one of the other tutorials available. I'll add an option to provide a choice of which lesson to run, eventually.

You can also use it as a template for your own experimentation with OpenGL.
