/**

* ( begin auto-generated from PShape.xml )

* Datatype for storing shapes. Processing can currently load and display

* SVG (Scalable Vector Graphics) shapes. Before a shape is used, it must

* be loaded with the loadShape() function. The shape()

* function is used to draw the shape to the display window. The

* PShape object contain a group of methods, linked below, that can

* operate on the shape data.

*

* The loadShape() function supports SVG files created with Inkscape

* and Adobe Illustrator. It is not a full SVG implementation, but offers

* some straightforward support for handling vector data.

* ( end auto-generated )

* <h3>Advanced</h3>

* In-progress class to handle shape data, currently to be considered of

* alpha or beta quality. Major structural work may be performed on this class

* after the release of Processing 1.0. Such changes may include:

* <ul>

* <li> addition of proper accessors to read shape vertex and coloring data

* (this is the second most important part of having a PShape class after all).

* <li> a means of creating PShape objects ala beginShape() and endShape().

* <li> load(), update(), and cache methods ala PImage, so that shapes can

* have renderer-specific optimizations, such as vertex arrays in OpenGL.

* <li> splitting this class into multiple classes to handle different

* varieties of shape data (primitives vs collections of vertices vs paths)

* <li> change of package declaration, for instance moving the code into

* package processing.shape (if the code grows too much).

* </ul>

* For the time being, this class and its shape() and loadShape() friends in

* PApplet exist as placeholders for more exciting things to come. If you'd

* like to work with this class, make a subclass (see how PShapeSVG works)

* and you can play with its internal methods all you like.

* Library developers are encouraged to create PShape objects when loading

* shape data, so that they can eventually hook into the bounty that will be

* the PShape interface, and the ease of loadShape() and shape().
