%
%  UpdatePixelViewIterator() iterates over the pixel view in parallel and calls
%  your update method for each scanline of the view.  The pixel region is
%  confined to the image canvas-- that is no negative offsets or widths or
%  heights that exceed the image dimension are permitted.  Updates to pixels
%  in your callback are automagically synced back to the image.
%
%  Use this pragma:
%
%    #pragma omp critical
%
%  to define a section of code in your callback update method that must be
%  executed by a single thread at a time.
%
%  The format of the UpdatePixelViewIterator method is:
%
%      MagickBooleanType UpdatePixelViewIterator(PixelView *source,
%        UpdatePixelViewMethod update,void *context)
%
%  A description of each parameter follows:
%
%    o source: the source pixel view.
%
%    o update: the update callback method.
%
%    o context: the user defined context.
