MapContext class abstract
MapContext is the rendering engine and the context in which virtual geographic maps get rendered.
It runs the render loop or offers the means for the user to run a custom one.
Data sources, assets and virtual maps can be attached to the context. A virtual map can only render data from sources attached to the same context.
The graphics backend to be used by the engine can be choosen by the user or a platform suitable one can be automatically selected internally. Only one graphics backend can be active and once selected it cannot be changed.
