With import of shapes in 3D-mode from pptx files, the internal values
for light level might be outside the range 0..100 and thus not allowed in
ODF. These high levels are needed to get a similar rendering to
MS Office.
The export to ODF clamps them now to the allowed range.
I do not intend to change the export to loext namespace, because the
extrusion mode of custom shapes needs a totally new handling. But that
will not be possible timely for version 24.8.
