Regina Henschel 6e5529d738 tdf#70039 convert 3D effects to extrusion
ODF allows a 3D mode for custom shapes. That can be used to render
some of the 3D effects possible in MS Office.

MS Office has not published, how they calculate the 3D-scenes. Thus
most principles and values are found by experiments. My assumptions
are contained as comments.

This current solution does not work well for perspectiveFront camera
with rotation on only y-axis or on only x-axis. If someone has an idea,
what is wrong in my solution or what MS Office might specially do,
please tell me.

The tests do not cover whether the rendering in LO is the same as in
MS Office. I have no idea how to write such tests. To test manually:
In Powerpoint: Copy the shape and set the copy to wireframe. Cut the
copy and insert it as svg image. Move the image so that the lines cover
the original shape. Save it. In LibreOffice: Open the file and set the
shape to wireframe. Now you can easily compare the rendering of
PowerPoint and LibreOffice.

Extrusion can be used for images, that have a 3D-scene applied like in
tdf#45495. That would work with this patch, but the related places are
commented out because of tdf#159515.

This patch does not cover lighting and material and it does not
contain export.

3D-text is not contained in the patch. There are principle problems
with 3D-text. Thus a solution requieres a lot, including additions to
the ODF standard.

The comments in tdf#70039 contain more about aspects, where MS Office
and ODF are in principle incompatible in regard to 3D-effects.
