bcb6638535 Found a bug in dividing and adding unique verticle segments which could 
cause the triangulator to end up in an infinite loop.  Basically the code
was correct, but the verticle line test was a bit to selective.

fc6eee819b Shuffled stl type names a bit. 
Began adding support for tri-fanning (or maybe other arrangments too.)

09aa6ba330 Handle corner nodes separately from the rest of the fitted nodes. 
Add fitted nodes in after corners and polygon nodes since the fitted nodes
  are less important.  Subsequent nodes will "snap" to previous nodes if
  they are "close enough."
Need to manually divide segments to prevent "T" intersetions which can
  confound the triangulator.  Hey, I got to use a recursive method!
Pass along correct triangle attributes to output file generator.
Do fine grained node snapping for corners and polygons, but course grain
  node snapping for fitted terrain nodes.

88dd015639 Removed Dem2node from the Tools fold. 
Tweaked the triangulator options to add quality mesh refinement.

033af0d05c Added a mechanism to dump out the triangle structures for viewing. 
Fixed a couple bugs in first pass at triangulation.
- needed to explicitely initialize the polygon accumulator in triangle.cxx
  before each polygon rather than depending on the default behavior.
- Fixed a problem with region attribute propagation where I wasn't generating
  the hole points correctly.

b4a9bde0e9 First mostly successful tile triangulation works. There's plenty of tweaking 
to do, but we are marching in the right direction.

45da0562fb Continue shaping the code towards triangulation bliss. Added code to 
calculate some point guaranteed to be inside a polygon.
