[OpenSCAD] Capacity & Optimization test case (Cory Doctorow's Makers cover model remix)

[Andrew Plumb]

Hi Clifford and Marius,

In the spirit of CC-licensed material, I've been trying to use  
OpenSCAD to do some simple remixing of Cory's Makers cover model.  See http://www.shapeways.com/model/76118/cory_doctorow_makers_cover_3d_print.html 
  for the STL model (~23MB).

I've attached a really simple wrapper script that boolean diff's the  
source model into top and bottom parts, then scales & maps the parts  
onto the front and back of a simple pendant-shaped scaffold.

The full "makers_pendant()" compiles fine.  OpenSCAD dies at Render  
(CGAL) time for even the simpler sub-parts like "makers_top()" or  
"makers_bottom()".

Andrew.
