/**
* Base class for all sketches that use processing.core.
* <p/>
* Note that you should not use AWT or Swing components inside a Processing
* applet. The surface is made to automatically update itself, and will cause
* problems with redraw of components drawn above it. If you'd like to
* integrate other Java components, see below.
* <p/>
* As of release 0145, Processing uses active mode rendering in all cases.
* All animation tasks happen on the "Processing Animation Thread". The
* setup() and draw() methods are handled by that thread, and events (like
* mouse movement and key presses, which are fired by the event dispatch
* thread or EDT) are queued to be (safely) handled at the end of draw().
* For code that needs to run on the EDT, use SwingUtilities.invokeLater().
* When doing so, be careful to synchronize between that code (since
* invokeLater() will make your code run from the EDT) and the Processing
* animation thread. Use of a callback function or the registerXxx() methods
* in PApplet can help ensure that your code doesn't do something naughty.
* <p/>
* As of release 0136 of Processing, we have discontinued support for versions
* of Java prior to 1.5. We don't have enough people to support it, and for a
* project of our size, we should be focusing on the future, rather than
* working around legacy Java code. In addition, Java 1.5 gives us access to
* better timing facilities which will improve the steadiness of animation.
* <p/>
* This class extends Applet instead of JApplet because 1) historically,
* we supported Java 1.1, which does not include Swing (without an
* additional, sizable, download), and 2) Swing is a bloated piece of crap.
* A Processing applet is a heavyweight AWT component, and can be used the
* same as any other AWT component, with or without Swing.
* <p/>
* Similarly, Processing runs in a Frame and not a JFrame. However, there's
* nothing to prevent you from embedding a PApplet into a JFrame, it's just
* that the base version uses a regular AWT frame because there's simply
* no need for swing in that context. If people want to use Swing, they can
* embed themselves as they wish.
* <p/>
* It is possible to use PApplet, along with core.jar in other projects.
* In addition to enabling you to use Java 1.5+ features with your sketch,
* this also allows you to embed a Processing drawing area into another Java
* application. This means you can use standard GUI controls with a Processing
* sketch. Because AWT and Swing GUI components cannot be used on top of a
* PApplet, you can instead embed the PApplet inside another GUI the way you
* would any other Component.
* <p/>
* It is also possible to resize the Processing window by including
* <tt>frame.setResizable(true)</tt> inside your <tt>setup()</tt> method.
* Note that the Java method <tt>frame.setSize()</tt> will not work unless
* you first set the frame to be resizable.
* <p/>
* Because the default animation thread will run at 60 frames per second,
* an embedded PApplet can make the parent sluggish. You can use frameRate()
* to make it update less often, or you can use noLoop() and loop() to disable
* and then re-enable looping. If you want to only update the sketch
* intermittently, use noLoop() inside setup(), and redraw() whenever
* the screen needs to be updated once (or loop() to re-enable the animation
* thread). The following example embeds a sketch and also uses the noLoop()
* and redraw() methods. You need not use noLoop() and redraw() when embedding
* if you want your application to animate continuously.
* <PRE>
* public class ExampleFrame extends Frame {
*
* public ExampleFrame() {
* super("Embedded PApplet");
*
* setLayout(new BorderLayout());
* PApplet embed = new Embedded();
* add(embed, BorderLayout.CENTER);
*
* // important to call this whenever embedding a PApplet.
* // It ensures that the animation thread is started and
* // that other internal variables are properly set.
* embed.init();
* }
* }
*
* public class Embedded extends PApplet {
*
* public void setup() {
* // original setup code here ...
* size(400, 400);
*
* // prevent thread from starving everything else
* noLoop();
* }
*
* public void draw() {
* // drawing code goes here
* }
*
* public void mousePressed() {
* // do something based on mouse movement
*
* // update the screen (run draw once)
* redraw();
* }
* }
* </PRE>
*
* <H2>Processing on multiple displays</H2>
* <P>I was asked about Processing with multiple displays, and for lack of a
* better place to document it, things will go here.</P>
* <P>You can address both screens by making a window the width of both,
* and the height of the maximum of both screens. In this case, do not use
* present mode, because that's exclusive to one screen. Basically it'll
* give you a PApplet that spans both screens. If using one half to control
* and the other half for graphics, you'd just have to put the 'live' stuff
* on one half of the canvas, the control stuff on the other. This works
* better in windows because on the mac we can't get rid of the menu bar
* unless it's running in present mode.</P>
* <P>For more control, you need to write straight java code that uses p5.
* You can create two windows, that are shown on two separate screens,
* that have their own PApplet. this is just one of the tradeoffs of one of
* the things that we don't support in p5 from within the environment
* itself (we must draw the line somewhere), because of how messy it would
* get to start talking about multiple screens. It's also not that tough to
* do by hand w/ some Java code.</P>

* <LI>Do not use "new PGraphicsXxxx()", use this method. This method

* <LI>The basic way to create bitmap images is to use the <A
* HREF="http://processing.org/reference/saveFrame_.html">saveFrame()</A>
* function.
* <LI>If you want to create a really large scene and write that,
* first make sure that you've allocated a lot of memory in the Preferences.
* <LI>If you want to create images that are larger than the screen,
* you should create your own PGraphics object, draw to that, and use
* <A HREF="http://processing.org/reference/save_.html">save()</A>.
* For now, it's best to use <A HREF="http://dev.processing.org/reference/everything/javadoc/processing/core/PGraphics3D.html">P3D</A> in this scenario.
* P2D is currently disabled, and the JAVA2D default will give mixed
* results. An example of using P3D:
* <PRE>
*
* PGraphics big;
*
* void setup() {
* big = createGraphics(3000, 3000, P3D);
*
* big.beginDraw();
* big.background(128);
* big.line(20, 1800, 1800, 900);
* // etc..
* big.endDraw();
*
* // make sure the file is written to the sketch folder
* big.save("big.tif");
* }
*
* </PRE>
* <LI>It's important to always wrap drawing to createGraphics() with
* beginDraw() and endDraw() (beginFrame() and endFrame() prior to
* revision 0115). The reason is that the renderer needs to know when
* drawing has stopped, so that it can update itself internally.
* This also handles calling the defaults() method, for people familiar
* with that.
* <LI>It's not possible to use createGraphics() with the OPENGL renderer,
* because it doesn't allow offscreen use.
* <LI>With Processing 0115 and later, it's possible to write images in
* formats other than the default .tga and .tiff. The exact formats and
* background information can be found in the developer's reference for
* <A HREF="http://dev.processing.org/reference/core/javadoc/processing/core/PImage.html#save(java.lang.String)">PImage.save()</A>.

* <A HREF="http://java.sun.com/j2se/1.3/docs/guide/2d/new_features.html">
* also supported</A>.
* <P>
* Generally, loadImage() should only be used during setup, because
* re-loading images inside draw() is likely to cause a significant
* delay while memory is allocated and the thread blocks while waiting
* for the image to load because loading is not asynchronous.
* <P>
* To load several images asynchronously, see more information in the
* FAQ about writing your own threaded image loading method.
* <P>
* As of 0096, returns null if no image of that name is found,
* rather than an error.
* <P>
* Release 0115 also provides support for reading TIFF and RLE-encoded
* Targa (.tga) files written by Processing via save() and saveFrame().
* Other TIFF and Targa files will probably not load, use a different
* format (gif, jpg and png are safest bets) when creating images with
* another application to use with Processing.
* <P>
* Also in release 0115, more image formats (BMP and others) can
* be read when using Java 1.4 and later. Because many people still
* use Java 1.1 and 1.3, these formats are not recommended for
* work that will be posted on the web. To get a list of possible
* image formats for use with Java 1.4 and later, use the following:
* <TT>println(javax.imageio.ImageIO.getReaderFormatNames())</TT>
* <P>
* Images are loaded via a byte array that is passed to
* Toolkit.createImage(). Unfortunately, we cannot use Applet.getImage()
* because it takes a URL argument, which would be a pain in the a--
* to make work consistently for online and local sketches.
* Sometimes this causes problems, resulting in issues like
* <A HREF="http://dev.processing.org/bugs/show_bug.cgi?id=279">Bug 279</A>
* and
* <A HREF="http://dev.processing.org/bugs/show_bug.cgi?id=305">Bug 305</A>.
* In release 0115, everything was instead run through javax.imageio,
* but that turned out to be very slow, see
* <A HREF="http://dev.processing.org/bugs/show_bug.cgi?id=392">Bug 392</A>.
* As a result, starting with 0116, the following happens:
* <UL>
* <LI>TGA and TIFF images are loaded using the internal load methods.
* <LI>JPG, GIF, and PNG images are loaded via loadBytes().
* <LI>If the image still isn't loaded, it's passed to javax.imageio.
* </UL>
* For releases 0116 and later, if you have problems such as those seen
* in Bugs 279 and 305, use Applet.getImage() instead. You'll be stuck
* with the limitations of getImage() (the headache of dealing with
* online/offline use). Set up your own MediaTracker, and pass the resulting
* java.awt.Image to the PImage constructor that takes an AWT image.

* methods to take more control of how the stream is read.
* <P>

* (Prior to 0096, die() would be called, killing the applet)
* <P>
* For 0096+, the "data" folder is exported intact with subfolders,
* and openStream() properly handles subdirectories from the data folder
* <P>
* If not online, this will also check to see if the user is asking
* for a file whose name isn't properly capitalized. This helps prevent
* issues when a sketch is exported to the web, where case sensitivity
* matters, as opposed to Windows and the Mac OS default where
* case sensitivity is preserved but ignored.
* <P>
* It is strongly recommended that libraries use this method to open
* data files, so that the loading sequence is handled in the same way
* as functions like loadBytes(), loadImage(), etc.
* <P>
* The filename passed in can be:
* <UL>
* <LI>A URL, for instance openStream("http://processing.org/");
* <LI>A file in the sketch's data folder

* changing over the next several releases.</B>
* <P>
* The simplest way to turn and applet into an application is to
* add the following code to your program:
* <PRE>static public void main(String args[]) {
* PApplet.main(new String[] { "YourSketchName" });
* }</PRE>
* This will properly launch your applet from a double-clickable
* .jar or from the command line.
* <PRE>
* Parameters useful for launching or also used by the PDE:
*
* --location=x,y upper-lefthand corner of where the applet
* should appear on screen. if not used,
* the default is to center on the main screen.
*
* --present put the applet into full screen presentation
* mode. requires java 1.4 or later.
*
* --exclusive use full screen exclusive mode when presenting.
* disables new windows or interaction with other
* monitors, this is like a "game" mode.
*
* --hide-stop use to hide the stop button in situations where
* you don't want to allow users to exit. also
* see the FAQ on information for capturing the ESC
* key when running in presentation mode.
*
* --stop-color=#xxxxxx color of the 'stop' text used to quit an
* sketch when it's in present mode.
*
* --bgcolor=#xxxxxx background color of the window.
*
* --sketch-path location of where to save files from functions
* like saveStrings() or saveFrame(). defaults to
* the folder that the java application was
* launched from, which means if this isn't set by
* the pde, everything goes into the same folder
* as processing.exe.
*
* --display=n set what display should be used by this applet.
* displays are numbered starting from 1.
*
* Parameters used by Processing when running via the PDE
*
* --external set when the applet is being used by the PDE
*
* --editor-location=x,y position of the upper-lefthand corner of the
* editor window, for placement of applet window
* </PRE>
