Test files for rotated Bezier curves

testBezSurf2.py creates a Bezier surface using 3 similar curves in XY, XZ, YZ planes.
In bezier3.fcstd I tried it in GUI. I drew a curve in XY plane, copied it two times and
rotated them into the two other planes. If I create the Bezier surface using these, it is totally planar.

The control points remain in the XY plane, only the curves get rotated. OCC computes the Bezier surface based on the control points.
