/**
* Subclass for PGraphics that implements the graphics API
* in Java 1.3+ using Java 2D.
*
* <p>Pixel operations too slow? As of release 0085 (the first beta),
* the default renderer uses Java2D. It's more accurate than the renderer
* used in alpha releases of Processing (it handles stroke caps and joins,
* and has better polygon tessellation), but it's super slow for handling
* pixels. At least until we get a chance to get the old 2D renderer
* (now called P2D) working in a similar fashion, you can use
* <TT>size(w, h, P3D)</TT> instead of <TT>size(w, h)</TT> which will
* be faster for general pixel flipping madness. </p>
*
* <p>To get access to the Java 2D "Graphics2D" object for the default
* renderer, use:
* <PRE>Graphics2D g2 = ((PGraphicsJava2D)g).g2;</PRE>
* This will let you do Java 2D stuff directly, but is not supported in
* any way shape or form. Which just means "have fun, but don't complain
* if it breaks."</p>
