Both C- and Python-coded API components were rearranged into logical groups. New Python modules are packaged as follows: freestyle - Top-level package freestyle.types - Classes for core data structues (e.g., view map) freestyle.chainingiterators - Pre-defined chaining iterators freestyle.functions - Pre-defined 0D and 1D functions freestyle.predicates - Pre-defined 0D and 1D predicates freestyle.shaders - Pre-defined stroke shaders freestyle.utils - Utility functions The Python modules are installed in scripts/freestyle/modules. Pre-defined styles are installed in scripts/freestyle/styles. To-do: update styles according to the new Freestyle API package structure.
