Summary0012179: vtkTensorGlyph bugs
Description1) fix orientation inversion causing flipped surface normals (see attached images). When the determinant of the transformation matrix is < 0 glyph and its surface normals are flipped. The attached patch fixes it by testing for this condition and applying an additional scale(-1,-1,-1).

2) Added names to generated output arrays so that they are recognized
by ParaView.

3) Override RequestUpdateExtent so that glyph source generates an whole
glyph when running in parallel, with out this only a piece of the glyph
is generated.

The attached images that illustrate the bug and the fix in ParaView make use of the data from VTKData/Data/tensors.vtk
Steps To ReproduceThe attached tarball contains a minimal program and test data to illustrate the flipped surface normals bug. The parallel bugs could be reproduced in ParaView using the tensor glyph plugin.

The fix for bug 1 needs more work, it breaks some of the tests.

OK, I updated the patch, tensor and header tests pass.
