[vtkusers] Writing a rotated vtkcubesource in a .vtp file

[Cory Quammen]

Ishan,

The actor->RotateZ(1); call rotates only the visible representation of the
cube, not the actual points that define the cube. Use
vtkTransformPolyDataFilter [1] to transform the cube source and save the
output of the transform filter.

HTH,
Cory
