Controls

Image lists are used to efficiently manage large sets of icons or bitmaps. All images in an image list are contained in a single, wide bitmap in screen device format. An image list may also include a monochrome bitmap that contains masks used to draw images transparently (icon style).  

The image list is capable of holding a large number of same sized images and retrieving them via their index within the range 0 to n - 1. The image list also has methods to facilitate storing, retrieving, and drawing of the stored images.
