following improvements: - When all unsupported entities (SOLIDS, TEXT, ...) have been filtered out from a block, dxfInsert::drawScene() was crashing because it assumed that the block was not empty. It now returns silently so the other blocks can still be imported. - The DXF reader assumed all vertices were read first, then the face indices. But, from the DXF "documentation" (www.autodesk.com/dxf) : "Polyface meshes created with the PFACE command are always generated with all the vertex coordinate entities first, followed by the face definition entities. The code within AutoCAD that processes polyface meshes requires this ordering. Programs that generate polyface meshes in DXF should generate all the vertices then all the faces. However, programs that read polyface meshes from DXF should be tolerant of odd vertex and face ordering." So now the importer ignores the posted number of vertices and face indices, and uses the size of the lists instead."
