Detailed Description
Class to facilitate getting an image from the disk into memory suitable for the current graphics backend.
ImageLoader objects simplify loading images from a wider variety of sources than is normally available for any one particular graphics backend. For instance, cairo only reads in png, but if we add Imlib or GraphicsMagick loaders, then the sky's the limit.
NOTES ON OTHER TOOLKIT IMPLEMENTATIONS:
gtk has module image loaders in lib directory. these are activated on call only.
implement: imlib loader graphicsmagick loader cairo loader
