- *    - Fix ImageList_DrawIndirect (rgbFg, rgbBk, dwRop).
- *    - Fix ImageList_SetFilter (undocumented).
- *      BTW does anybody know anything about this function???
- *        - It removes 12 Bytes from the stack (3 Parameters).

- *        - Second parameter COULD be an index?????
- *        - Third parameter.... ?????????????????????
+ *    - Fix ImageList_DrawIndirect (dwRop).
  *    - Add support for ILD_PRESERVEALPHA, ILD_SCALE, ILD_DPISCALE
  *    - Add support for ILS_GLOW, ILS_SHADOW, ILS_SATURATE, ILS_ALPHA

  *  Comments:
- *    - ImageList_Draw, ImageList_DrawEx and ImageList_GetIcon use
