5a4d9554df err message tweak in star() 
rearranged polygon_line_intersection to handle 2d and fixed
but where it didn't test polygon membership correctly.  Also
there was a bug with use of the bounded argument.
Added Ronaldo's triangulation.

ce0b4e9d32 internal: can set bevel to true and get non-garbage result 
bevel is always set by thread depth
   acme takes tpi
   square threads are at angle 0
   added generic_threaded_{rod,nut}
   eliminated metric_trapezoidal_*
   cleaned up matrices some in generic_threaded_rod
   threaded_rod can produce spec-true ISO/UTS profile with a triplet input for the diameter.
   Added bevel1 and bevel2 to all modules.  Made default uniformly false for every case instead of
       sometimes true, sometimes false
   Profiles that go over zero are not clipped, and bevels are based on actual profile top, not nominal
   When bevel is given to nuts it bevels the outside of the nut by thread depth
   higbee looks best with quincunx, but it's more expensive.  Select quincunx when higbee is used, min_edge otherwise
   Current code uses difference to remove excess length in the rod.  This gives faster renders at the cost
      of more complex code and green top/bottom surfaces.
   Changed slop to 4 * $slop.  I got good results printing with $slop=0.05 with this setting.
   Don't generate excess threads when starts>1, and don't force threads to be even
