* 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.
