Write a soy.bodies.Light.render method which, when a size property is set, renders a circle which always faces the camera in the specified size using the diffuse color of the light. A VBO triangle fan is the most efficient way to do this. Size should default to 0, while its set to zero the render method should return immediately.

Add a size property to the PySoy Light class so this can be easily tested. If you want to get fancy, try to make this look cooler with a blending of the light's color components from the center of the circle to the outside.
