 o Some invalid DXF data gets pass the import checks and breaks the tessing code
 o Tesselation via GLU sometimes produces strange results
 o Export STL: Exports existing CGAL model even though the current model is changed, but not CGAL rendered
+o It's now possible to start a new rendering while one is already running.
+  -> turn off most (or all) interaction while rendering
 
 CRASH BUGS
 ----------
 o Broken polyhedron() entities are not correctly detected and cause CGAL segfaults
 o Non-manifold objects make CGAL crash (e.g. two cubes which touch at one edge)
