Import of 3D-Image from pptx

[Regina Henschel <rb.henschel@xxxxxxxxxxx>]

Hi all,

at the moment, a 3D image is imported as an image and displayed in 
Impress without 3D. The 3D properties are in the InteropGrabBag and are 
written out again on export, in addition to a rotation or mirroring that 
the user has made with the image in LO.

The 3D image could be treated in the same way as an image that has been 
cropped to a shape in PowerPoint. Such an image is imported as a custom 
shape with bitmap filling. Such a custom shape can then be displayed in 
3D mode. When saving, however, as with the cropped image, the result 
would not be a pure image but a shape with a bitmap fill.

What do you think? Should I implement this or should I continue to 
import a 3D image as a pure image?

Kind regards,
Regina
