- * wxImageList is used for wxListCtrl, wxTreeCtrl. These controls refer to
- * images for their items by an index into an image list.
- * A wxImageList is capable of creating images with optional masks from
- * 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.
