Summary:                    vtkTensorGlyph bugs
Description: 
1) fix orientation inversion causing flipped surface normals. When the
determinant of the transformation matrix is < 0 surface normals are
flipped. The patch fizes 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.

note: The test needs to be updated as well, as it takes measures to hide
bug 1, commments in the existing test describe this.
