IDirectFBSurface   SetDstColorKeyIndex

Set the destination color key like with SetDstColorKey() but using an index to the color/alpha lookup table.

SetDstColorKeyIndex (
  IDirectFBSurface   * thiz,
  unsigned int   index
);

This method is only supported by surfaces with an indexed pixelformat, e.g. DSPF_LUT8. For these formats this method should be used instead of SetDstColorKey().
