Detailed Description

State machine for rendering a scene; you can add attributes to the context, and also push & pop the current context.

The context maintains a list of the attributes (i.e., state variables), and can conceptually pop or push that list from/to a stack. In fact attributes are only pushed / popped on a need-to basis, to avoid the overhead of copying the entire list each time.
