goat3d

annotate libs/vmath/basis.h @ 40:a5c5cec3cb88

- added mesh attribute and face append functions - added Int4 constructor - continued the blender exporter - fixed a bug in clean_filename which made it produce unterminated strings - renamed clean_filename to goat3d_clean_filename and made it extern - added call to goat3d_clean_filename in the mesh XML export code to cleanup ctm filenames
