/**
 * Hacked from Werner Randelshofer's QuickTimeWriter demo. The original version
 * can be found <a href="http://www.randelshofer.ch/blog/2010/10/writing-quicktime-movies-in-pure-java/">here</a>.
 * <p>
 * A more up-to-date version of the project seems to be 
 * <a href="http://www.randelshofer.ch/monte/">here</a>.
 * If someone would like to help us update the encoder, that'd be great.
 * <p>
 * Broken out as a separate project because the license (CC) probably isn't 
 * compatible with the rest of Processing and we don't want any confusion.
 * <p>
 * Added JAI ImageIO to support lots of other image file formats [131008].
 * Also copied the Processing TGA implementation.
 * <p>
 * Added support for the gamma ('gama') atom [131008].
 * <p>
 * A few more notes on the implementation:
 * <ul>
 * <li> The dialog box is super ugly. It's a hacked up version of the previous
 *      interface, but I'm too scared to pull that GUI layout code apart.
 * <li> The 'None' compressor seems to have bugs, so just disabled it instead.
 * <li> The 'pass through' option seems to be broken, so it's been removed. 
 *      In its place is an option to use the same width/height as the originals.
 * <li> When this new 'pass through' is set, there's some nastiness with how
 *      the 'final' width/height variables are passed to the movie maker.
 *      This is an easy fix but needs a couple minutes.
 * </ul>
