%  ApplyImageOperator() apply one simple image operation to just the current
%  image.
%
%  The image in the list may be modified in three different ways...
%
%    * directly modified (EG: -negate, -gamma, -level, -annotate, -draw),
%    * replaced by a new image (EG: -spread, -resize, -rotate, -morphology)
%    * replace by a list of images (-separate and -crop only!)
%
%  In each case the result is returned into the list, and the pointer to the
%  modified image (last image added if replaced by a list of images) is
%  returned.  As the image pointed to may be replaced, the first image in the
%  list may also change.  GetFirstImageInList() should be used by caller if
%  they wish return the Image pointer to the first image in list.
%
%  The format of the ApplyImageOperator method is:
%
%    MagickBooleanType ApplyImageOperator(MagickWand *wand,
%        const int argc,const char **argv)
%
%  A description of each parameter follows:
%
%    o wand: The CLI wand holding all the settings and pointer to image
%
%    o argc: Specifies a pointer to an integer describing the number of
%      elements in the argument vector.
%
%    o argv: Specifies a pointer to a text array containing the command line
%      arguments.
%
%    o exception: return any errors or warnings in this structure.
