Detailed Description

The render engine class draws all drawable objects onto a gtk widget that it creates.

the render engine creates the gtk widget for drawing openGL stuff onto, it holds vectors of objects to be drawn and not drawn. It contains camera position, and animation information. All of the gtkglext stuff happens here
