/**

* 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.
