/**
* A simple library to write DXF files with Processing.
* Because this is used with beginRaw() and endRaw(), only individual
* triangles and (discontinuous) line segments will be written to the file.
* <p>
* Use something like a keyPressed() in PApplet to trigger it,
* to avoid writing a bazillion .dxf files.
* <p>
* Usually, the file will be saved to the sketch's folder.
* Use Sketch → Show Sketch Folder to see it from the PDE.
* <p>
* A simple example of how to use:
* <PRE>
* import processing.dxf.*;
*
* boolean record;
*
* void setup() {
* size(500, 500, P3D);
* }
*
* void keyPressed() {
* // use a key press so that it doesn't make a million files
* if (key == 'r') record = true;
* }
*
* void draw() {
* if (record) {
* beginRaw(DXF, "output.dxf");
* }
*
* // do all your drawing here
*
* if (record) {
* endRaw();
* record = false;
* }
* }
* </PRE>
* or to use it and be able to control the current layer:
* <PRE>
* import processing.dxf.*;
*
* boolean record;
* RawDXF dxf;
*
* void setup() {
* size(500, 500, P3D);
* }
*
* void keyPressed() {
* // use a key press so that it doesn't make a million files
* if (key == 'r') record = true;
* }
*
* void draw() {
* if (record) {
* dxf = (RawDXF) createGraphics(width, height, DXF, "output.dxf");
* beginRaw(dxf);
* }
*
* // do all your drawing here, and to set the layer, call:
* // if (record) {
* // dxf.setLayer(num);
* // }
* // where 'num' is an integer.
* // the default is zero, or you can set it to whatever.
*
* if (record) {
* endRaw();
* record = false;
* dxf = null;
* }
* }
* </PRE>
* Note that even though this class is a subclass of PGraphics, it only
* implements the parts of the API that are necessary for beginRaw/endRaw.
* <p>
* Based on the original DXF writer from Simon Greenwold, February 2004.
* Updated for Processing 0070 by Ben Fry in September 2004,
* and again for Processing beta in April 2005.
* Rewritten to support beginRaw/endRaw by Ben Fry in February 2006.
* Updated again for inclusion as a core library in March 2006.
* Constructor modifications in September 2008 as we approach 1.0.
