/*****************************************************************************
* A convenience class for loading icons from images.
*
* Icons loaded from this class are formatted to fit within the required
* dimension (16x16, 32x32, or 128x128). If the source image is larger than the
* target dimension, it is shrunk down to the minimum size that will fit. If it
* is smaller, then it is only scaled up if the new scale can be a per-pixel
* linear scale (i.e., x2, x3, x4, etc). In both cases, the image's width/height
* ratio is kept the same as the source image.
