* a variety of sources - a single bitmap plus a colour to indicate the mask,
* two bitmaps, or an icon.
*
+ * Image lists can also create and draw images used for drag and drop functionality.
+ * This is not yet implemented in wxImageList. We need to discuss a generic API
+ * for doing drag and drop and see whether it ties in with the Win95 view of it.
+ * See below for candidate functions and an explanation of how they might be
+ * used.
