All Implemented Interfaces:

PConstants
```
public class FrameBuffer
extends Object
implements PConstants
```
Encapsulates a Frame Buffer Object for offscreen rendering. When created with onscreen == true, it represents the normal framebuffer. Needed by the stack mechanism in OPENGL2 to return to onscreen rendering after a sequence of pushFramebuffer calls. It transparently handles the situations when the FBO extension is not available. By Andres Colubri.
