org.locationtech.udig.project.render.ICompositeRenderContext
A toolkit that is provided to composite renderers.
In addition to the references available in the Toolkit class, RenderToolkit has the layers and services the renderer is responsible for and the buffered image that the renderer draws to.

Responsibilities:
- Provide access to the objects that an extension can use for its operations.
- Provide convenience methods for extension developers to use.
- Provide a consistent interface for extensions which will not easily change in future versions
