2.5.0: Bug fixes. Do a coordinate transformation to fix the mirrored part bug when writing POV files. Fix reading binary files. 2.4.4: build infrastructure tweaks mostly. 2.4.3: Fix reading big binary files on windows. 2.4.2: Reduced some errors to warnings. Made the program somewhat more informative. 2.4.1: Add status reporting to monitor progress, especially on big files. 2.4.0: Add option to set allowed distance between vertexes that are assumed to be the same. 2.3.0: Follow the new syntax for povray: use 'triangle' instead of 'facet'. 2.2.0: Changed to BSD-style license.
