/*
* ImageList implementation
*
* Copyright 1998 Eric Kohl
*
* TODO:
* - Fix ImageList_DrawIndirect (xBitmap, yBitmap, rgbFg, rgbBk, dwRop).
* - Fix ImageList_GetIcon.
* - Fix drag functions.
* - Fix ImageList_Read and ImageList_Write.
* - Fix 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.... ?????????????????????
*
* 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.
