/**
* Create Graphics.
*
* The createGraphics() function creates an object from the PGraphics class
* (PGraphics is the main graphics and rendering context for Processing).
* The beginDraw() method is necessary to prepare for drawing and endDraw() is
* necessary to finish. Use this class if you need to draw into an off-screen
* graphics buffer or to maintain two contexts with different properties.
