Yes. I have introduced a new flag "MetalColored" as property and have 
add a new item to the "Surface" drop-down list in the "3D-Settings" 
toolbar. The user can use a preset "Metal ODF" to get ODF rendering and 
a preset "Metal MSO" to get MS Office kind of rendering. (Exact wording 
for labels under discussion.)

Thank you for your offer.

After some struggling I think I have got it now. Patch in Gerrit is 
updated accordingly.
