* TODO:
* - 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).
* - First parameter SHOULD be a HIMAGELIST.
* - 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
* ImageList_DrawIndirect. Since ImageList_DrawIndirect is still
* partially implemented, the functions mentioned above will be
* limited in functionality too.

* - Hotspot handling still not correct. The Hotspot passed to BeginDrag
* is the offset of the image position relative to the actual mouse pointer
* position. However the Hotspot passed to SetDragCursorImage is the
