Hi,
I'm creating a complex GUI with jpct and need to use multi threading in many parts.

When multiple threads then try to calculate the normals of objects at the same time I get an exception like:
java.lang.ArrayIndexOutOfBoundsException: index=40 length=29
at com.threed.jpct.Mesh.calcNormalsFast(Mesh.java:988)
at com.threed.jpct.Mesh.calcNormals(Mesh.java:543)
at com.threed.jpct.Object3D.calcNormals(Object3D.java:3336)

It would really great if you could modify it to allow multi threading!

Thanks!
