aramis_acg ad759f6efe - Ifc: use a combination of clipper and poly2tri to triangulate arbitrary polygons with arbitrarily-shaped holes (the former to workaround the cases not supported by the latter ...). Issues with doors et al. (i.e. openings touching the outer contour of a wall polygon) remain and are yet to be solved. Overall, this change should make IfcLoader much more robust, though. Since this means that the previous algorithm to triangulate walls is dropped altogether, regressions are highly likely.
Note 1: there are cases in which the previous algorithm may have produced 'better' triangles, but my big hope is that poly2tri's CDT implementation will implement more advanced refinement algorithms over time.

Note 2: This issue http://code.google.com/p/poly2tri/issues/detail?id=34 is relevant, first versions of my poly2tri embedding would indeed stackoverflow or assert. I somehow avoided this by using Clipper as prepass and scaling the entire polygon to 0..1 range (as recommended).

This patch replaces »continously« with »continuously« and »treshold« with »threshold«.

aramis_acg 81ad224f84 - IFC: Refactor source to simplify maintenance.
- IFC: rate all available representations by a simple ranking system and take the one that is easiest to load. This should avoid loading the same geometry twice. Also it might result in quality improvements when BRep geometry is avoided in favour of extrusion geometry.
# IFC: Various bugfixes related to geometry loading.
