-/// Immediate mode renderer.
-///
-/// The renderer caches state changes in memory and only programs the underlying
-/// shader program when a draw call is issued and if anything has changed. This
-/// keeps the number of graphics API calls to a minimum, but requires tracking
-/// state changes. The 'changed' booleans below fulfill this purpose, and
-/// indicate whether a given state has changed since the last draw call.
-///
-/// The renderer must combine state changes accordingly. For example, if only
-/// the lights have changed, then it is sufficient to update light uniforms in
-/// the current shader program. On the other hand, if the shader program has
-/// changed, then the renderer must reconfigure it from scratch and set light
-/// uniforms, camera uniforms, etc.
-///
-/// Note that the shader program API has its own level of caching as well, so
-/// reconfiguration at the level of the renderer does not result in the
-/// worst-case set of graphics API calls.
