I think I should warn people that the DIBitmap class and all interfaces
which use it will disappear in Beta. They will be replaced by a more
general ImageProducer/ImageConsumer interface that will more generally
control the flow of image information from its source to any interested
parties.
DIBitmaps are the only way to prototype ways of creating images in the
Alpha APIs, but they are restricted to 8-bit colormapped images and have
absolutely no support for streaming image data (i.e. incrementally
rendering images as they are downloaded) so a new mechanism was developed
and will appear in the Beta APIs.
