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