%  DrawSetViewbox() sets the overall canvas size to be recorded with the
%  drawing vector data.  Usually this will be specified using the same
%  size as the canvas image.  When the vector data is saved to SVG or MVG
%  formats, the viewbox is use to specify the size of the canvas image that
%  a viewer will render the vector data on.
%
%  The format of the DrawSetViewbox method is:
%
%      void DrawSetViewbox(DrawingWand *drawing_wand,unsigned long x1,
%        unsigned long y1,unsigned long x2,unsigned long y2)
%
%  A description of each parameter follows:
%
%    o drawing_wand: The drawing wand.
%
%    o x1: left x ordinate
%
%    o y1: top y ordinate
%
%    o x2: right x ordinate
%
%    o y2: bottom y ordinate
