Renderer (MultimediaLib 2020.2 API)

All Known Implementing Classes:

AbstractRenderer, GDXRenderer, HeadlessRenderer, Java2DRenderer, TeaRenderer
```
public interface Renderer
```
Renders audiovisual data to that can be used to display multimedia applications. A Renderer instance acts as the access point for platform resources such as graphics, sound, and input devices.
When started, the renderer will create the display system and then start the animation loop. Frame updates will be scheduled to match the desired framerate, although this might not be possible depending on the current platform and the amount and complexity of graphics that are drawn.
All interaction with the renderer should be done from callbacks that are called during the animation loop. The Scene interface splits the application into different phases.
The renderer has two concepts of display size: the screen and the canvas. The screen is the entire available drawing surface, excluding any title and status bars and borders. The screen size can change, for example when the window is resized or when the device changes orientation. The canvas is the drawing area that the game uses. Transitioning between these two sets of coordinates is handled by the Canvas.
