This patch adds some new functionality to the Freestyle Python API, notably: - MaterialBP1D, checks whether the supplied arguments have the same material - Fixes a potential crash in CurvePoint.fedge (due to NULL pointer) - Makes (error handling in) boolean predicates more robust - Adds a BoundingBox type, to make working with bounding boxes easier - Adds several new functions (get_object_name, get_strokes, is_poly_clockwise, material_from_fedge) - Adds a StrokeCollector StrokeShader, that collects all the strokes from a specific call to Operators.create() - Adds hashing and rich comparison to the FrsMaterial type These new features (most of them, anyway) are needed for making a more robust SVG exporter that supports holes in fills.
