Refactored renderer

Renderer is basically now more C++'y, as it makes more use of classes (a lot of GL types have been wrapped), and the renderer itself is now a class. The monitor mesh is also now indexed.

Tweaked the NTSC artifacting after inadvertently fixing a bug with the way the image was loaded.
