  23  * wxImageList is used for wxListCtrl, wxTreeCtrl. These controls refer to
  24  * images for their items by an index into an image list.
  25  * A wxImageList is capable of creating images with optional masks from
  26  * a variety of sources - a single bitmap plus a colour to indicate the mask,
  27  * two bitmaps, or an icon.
  28  *
  29  * Image lists can also create and draw images used for drag and drop functionality.
  30  * This is not yet implemented in wxImageList. We need to discuss a generic API
  31  * for doing drag and drop and see whether it ties in with the Win95 view of it.
  32  * See below for candidate functions and an explanation of how they might be
  33  * used.
