Shows how to use the Demo Frameworks 'basic' 2d rendering capabilities that work across all backends. The basic2D interface allows you to render ASCII strings using a system provided font and draw colored points.
The functionality in Basic2D is used internally in the framework to render the profiling overlays like the frame rate counter and graph.
Shows how to use the G2D API blit functions to create a multiplane/multilayer landscape. The layers are rendered to the FB directly without having the need of using other APIs.
