Fixed issue that caused non-zero exist code
* For some reason that can't be explianed passing in a const string as an arg to GS DLL caused exit code to be reported as non-zero (but files generated). Address this by strdup'ing the appended "-dSAFER" argument. * Added some example PS and PDF files to assist with testing (TODO : clean up test script and check in). * Rolled release to version 1.2

% If you're concerned that the cpu in your PostScript printer will atrophy
|
||||
% from disuse, here is another Escher-like contribution to to keep it busy
|

% for a while. It uses PostScript color commands, but will still work on
|
||||
% a monochrome printer (but isn't very pretty in black & white).
|

%
|
||||
% The butterflies are arranged in a hexagonal grid (wallpaper group p6),
|
||||
% and the moveto, lineto, curveto commands used to render the tesselation
|
||||
% are redefined so as to impose a nonlinear transform that shrinks the
|
||||
% infinite plane to an ellipse. This is a sleazy way to mimic Escher's
|
||||
% "circle limit" sorts of things.
|
||||
%
|
||||
% The butterfly permimeter was made by imposing all the symmetry constraints
|
||||
% on a path, and then that path was filled in using Adobe Illustrator
|
||||
%
|
||||
% The routines Xform and next_color are easy to change if you want to hack
|

% with them. The code was written to sacrifice efficiency for readability.
