 The PImage.pixels[] array (separate from the other pixels[] array, which is global) always represents the picture, even when part of it is made non-visible. This is quite useful... I wish I had figured that out earlier. The PImage.pixels[] array (separate from the other pixels[] array, which is global) always represents the picture, even when part of it is made non-visible.

 +When using the PImage.pixels[] array:
 +  * Don't have to use loadPixels()
 +  * Use get() and set() to change color values
 +  * Have to use PImage.updatePixels()
 +  * Have to call image() after updating pixels.
 +
 +When using the global pixels[] array:
 +  * Call loadPixels()
 +  * Change the array- direct access
 +  * Call updatePixels()
 +  * No need to call image() again- pixels[] is re-read during every call to draw()
