Base class for enqueuing rendering operations in a single-threaded rendering environment. Instead of each operation being rendered immediately by the underlying graphics library, the operation will be added to the provided RenderQueue, which will be processed at a later time by a single thread. This class provides implementations of drawLine(), drawRect(), drawPoly(), fillRect(), draw(Shape), and fill(Shape), which are useful for a hardware-accelerated renderer. The other draw*() and fill*() methods simply delegate to draw(Shape) and fill(Shape), respectively.
