Add a missing "=" to create a valid SVG for ellipses.
I accidentally stumbled upon a way to actually get an ellipse in SVG by
tilting a cylinder. If I tilt the cylinder via the `ObjectPlacement` of
the `IfcProduct` I get an ellipse. If I set the `ExtrudedDirection` of
the `IfcExtrudedAreasolid`, however, I get a sampled path.
* Implementation of BVH tree for IFC files using NCollection_UBTree
* Fixes for gcc and OCCT < v6.8
* Enable BVH selection by TopoDS_Shape
* Small fixes to tree
* Merge conflicted files and other changes
* Eliminate one warning (some remain) + add tree test
- Allow opening of non-latin filenames on Windows, by using the non-standard _wfopen(), meaning that the IfcSpfStream no longer relies on a std::istream but a FILE* descriptor
Fix a bug in the formatting of IFC simple types
Provide a way of iterating over all entities in the IFC file
Added IFC test file by Ryan Schultz
Added another IFC test file from AutoCAD Architecture 2010
- Allow accessing entities by GlobalId
- Some more support for writing back IFC
- Prefix EXPRESS Enum values to avoid collisions
- Fix a bug in the SenseAgreement of Cartesian trimmed curves
- Use straight line segment in case point projection failed on trimmed curve
- Add epsilon to polylines and -loops point equality test
- Decompose a convex polygonal bounded halfspace into several unbounded halfspace and process only if they operate on a volume larger than some epsilon
- No longer fail connected facesets if a single face is invalid
- Updated IfcBlender for compatibility with Blender 2.62
- Added additional test files
- Automatic tests for several well known IFC files on the Internet
- IfcBlender: Make visibility in render consistent with 3d view
- Some compatibility for Ifc2x files with IfcShapeRepresentations and RepresentationIdentifier 'IAI'
