Detailed Description
This is the base class of anything renderable! We use this class to handle renderable objects that can have simple geometry such as triangles, spheres, etc.
Rendering primitive parent class. These objects are usually created by a 'Primitive' subclass when rendering is done. The primary difference between two classes is that the 'Primitive' always remains in scene space, or world space, and a rPrimitive is allocated per render sample and transformed into clip and screen space. These objects are destroyed after rendering is complete.

Clip this primitive, transform it to screen space, and add it to the list of primitives to render in the Scene.
The return value is true if this was added to the list. Originally this was used to indicate clipping. However implementations are now allowed to create other rPrimitive instances and add them to the list (for clipping into multiple pieces). If false is returned, this is immediately deleted. If true is returned it is assumed that destroying the Scene list will delete the primitive.
Implemented in DD::Image::rTriangle, and DD::Image::rPoint.
