- Created Example2/main.c from Example/main.c that:
  - Uses GLUT instead of SDL due to SDL having compile problems on OSX
    10.9.
  - Doesn't depend on nanosvg as the provided bg.svg caused tessellation
    failures at certain ranges of 't'.

- Added debug messages to tess.c when DEBUG is defined.

Tested on OSX 10.9 using Eclipse C++.
