Improved boundary data input format . Improved geometric calculations . Earlier versions used simple floating point arithmetic to determine these things, and sometimes ran into trouble as a result. This version incorporates adaptive-precision versions of these predicates that were developed by Jonathon Shewchuk of U California, Berkeley, while he was a PhD student at Carnegie Mellon University. File name changes .
Minor bug fixes .
All but a couple of the problem input files sent to me after version 0.1.6 now work. These changes affect all cases where quotes are used in template files, so check any template files you have created to make sure they are compatible with the new form of quote handling. This required a large number of small changes, with three common causes. This cleanup should also improve portability to other new platforms, especially those with cfront -based compilers.
