%  ColorMatch() returns true if two pixels are identical in color.
%
%  The format of the ColorMatch method is:
%
%      void ColorMatch(const PixelPacket *p,const PixelPacket *q,
%        const double fuzz)
%
%  A description of each parameter follows:
%
%    o p: Pixel p.
%
%    o q: Pixel q.
%
%    o distance:  Define how much tolerance is acceptable to consider
%      two colors as the same.
