/*
 *  ImageList implementation
 *
 *  Copyright 1998 Eric Kohl
 *
 *  TODO:
 *    - Improve the documentation.
 *    - Improve error checking in some functions.
 *    - Fix ILD_TRANSPARENT error in ImageList_DrawIndirect.
 *    - Fix offsets in ImageList_DrawIndirect.
 *    - Fix ImageList_GetIcon (might be a result of the
 *      ILD_TRANSPARENT error in ImageList_DrawIndirect).
 *    - Fix drag functions.
 *    - Fix all other stubs.
 *    - Add ImageList_SetFilter (undocumented).
 *      BTW does anybody know anything about this function???
 *        - It removes 12 Bytes from the stack (3 Parameters).
 *        - First parameter SHOULD be a HIMAGELIST.
 *        - Second parameter COULD be an index?????
 *        - Third parameter.... ?????????????????????
 *
 *  Testing:
 *    - Test ImageList_GetImageRect (undocumented).
 *    - Test all the other functions.
 *
 *  Comments:
 *    - ImageList_Draw, ImageList_DrawEx and ImageList_GetIcon use
 *      ImageList_DrawIndirect. Since ImageList_DrawIndirect is still
 *      partially imlemented, the functions mentioned above will be 
 *      limited in functionality too.
