BUG: Glyph3DMapper get method returns incorrect string
vtkGlyph3DMapper::GetOrientationModeAsString() does not check for vtkGlyph3DMapper::ROTATION. Rather it checks for vtkGlyph3DMapper::ORIENTATION which is not one of the valid settings.
glyph->SetOrientationModeToRotation() followed by glyph->GetOrientationModeAsString() returns "Invalid" rather than "Rotation".
