now doing normal rendering through frame buffer objects, although not quite integrated yet.
enabled depth-only FBO for shadow mapping
shadow fbo now fully enabled and correct.  Still need to get the drawing working.
draw_shadow() not giving any errors anymore, but shadow shading not yet implemented.
mesh objects now print in console properly.
uncommented some lines to restore some functionality
debugging mode. Commenting out stuff to see what doesn't fit.

getting closer to figuring this out.
shadows are working!  Needs a lot of cleaning up and debugging, though.
small improvements
updated demo
fps clock now working with draw_shadow
created scene.enable_cubemap_fbo().  Seems to be working so far, now just need to get a draw function for it.
merged basic, texture, and shadow shaders into one combShader.  Starting to refactor code to take all cases into account without significant code duplication.

shadows and textures now work together, just need to clean that interaction up a bit.
shadow rendering now optional.  Just call scene.render_shadow() in draw loop to do it.
bit of cleaning.
cleaned up testShader2.py
