% SetImageProgressMonitor() sets the image progress monitor to the specified
% method and returns the previous progress monitor if any. The progress
% monitor method looks like this:
%
% MagickBooleanType MagickProgressMonitor(const char *text,
% const MagickOffsetType offset,const MagickSizeType extent,
% void *client_data)
%
% If the progress monitor returns MagickFalse, the current operation is
% interrupted.
%
% The format of the SetImageProgressMonitor method is:
%
% MagickProgressMonitor SetImageProgressMonitor(Image *image,
% const MagickProgressMonitor progress_monitor,void *client_data)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o progress_monitor: Specifies a pointer to a method to monitor progress of
% an image operation.
%
% o client_data: Specifies a pointer to any client data.
