This function draws an Intuition Image structure in a variety of "visual states", these include:
Only IDS_NORMAL will make sense for traditional Image structures, this function is more useful when applied to new custom images or "object-oriented image classes."
Each class of custom images is responsible for documenting which visual states it supports, and you typically want to use images which support the appropriate states with your custom gadgets.
The DrawInfo parameter provides information invaluable to "rendered" images, such as pen color and resolution. Each image class must document whether this parameter is required.
