The patch it a continuation of commit 6e5529d7, that handles import of
the 3D-scene camera. This patch handles lighting of the 3D-scene. But
lighting in MS Office has features which we cannot yet render, address
in API or store in ODF. More than two lights, softing with Scale and
and Offset, or Specular/Diffuse for all lights are not implemented for
extruded shapes, for example. Thus the rendering results cannot be
equal to MS Office.
This patch contains a lot of workarounds and compromises to get a
rendering which looks somewhat similar. Unit tests are not really
meaningful in this situation. The included tests focus on the principle
aspects modern/legacy lightRigs and lightRig rotation.
The light rig values are taken from sections 2.1.1274 and 2.1.1321 in
[MS-OI29500] - v20231113.

That version does not specify the used coordinate system for the
light directions. Find the discussion about that in
https://learn.microsoft.com/en-us/answers/questions/1551836
topic: LightDirection on shape with 3D effect is rendered different
than specified.
That version does not specify the values 'Specular' and 'Diffuse'
for legacy* light rigs. Find the discussion about that in
https://learn.microsoft.com/en-us/answers/questions/1608333
topic: What is 'Specular' and 'Diffuse' in the lightRig table in
section 2.1.1274 in [MS-OI29500]?
