-/**
-A class for supervising the rendering process.  While many Renderables (in
-particular, Objects and Scenes) can by rendered without a Renderer, using one
-will often be more efficient.  This is especially true for ObjectInstances.
-
-The Renderer works by deferring GL state changes until something is actually
-being drawn.  This avoids many unnecessary GL calls if consecutive renderables
-use the same resources.
-
-A state stack is provided to help with state scoping.  Typically a Renderable
-will push the current state on entry, set whatever state it requires, render
-itself, and pop the state when it's done.  An RAII helper class is provided for
-the push/pop operation.
