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