I've started to comment the Icon Mangler code. The first step was do "function headers", where I described the input and output of each function, had a simple description of what it did and notes if there was anything that should be kept in mind when using it. Ideally this would have been done in the beginning, as part of my top-down design, but I couln't really since I was learning how to do an icon editor at the same time. Eitherway, this hasn't been too hard, the only problems that I've encountered (other than boredom) are than some of my early code (I've started the commenting process with the base icnsClass) is rather messy and inefficient, so I'm getting tempted to rewrite it.
