  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.
