Bug List:
---------
Priority 0-5, 5 is worst:

- [3] Some reports of mesh showing up with broken polygons (they are quads, so I think this is because of faulty normal interpolation)
- [3] Some Ubuntu user has problems with loosing the cursor in the edit view (I can not reproduce this in my VM-Ware)
- [2] Triangles does not support ClassID
- [2] Face Culling does not work for boxes, when coordinates are flipped.
- [2] A self-refering cycle of rule retirements would crash structure synth.
- [2] Parser do not allow operator names as rule names. 'rule R1 maxdepth 2 > c ' fails.
- [1] Syntax Highlightning has several errors.
