org.locationtech.udig.project.render.IRenderManager
Used by the map viewers/editors to manage the rendering process. Responsibilities:
- Respond to model change events and start rendering processes depending on the event. For example: If the Map CRS is changed then all layers must be rerendered with the new CRS.
- Create Renderers when a map editor is opened.
- Create and remove renderers when renderers are added or removed
