Ah, okay. Thanks for the explanation!

From my point-of-view, that would be fine.

Ah, perfect! That makes clear how they solved the issue in the mail I've
mentioned (sent on the Design list) - it was about how they get the
naturally "shadowed" edges:

Ah, you mean the internal one that is also used for drawing objects.
Personally, I don't know if the implementation is efficient - I just
noticed some drawing bugs in the past.

Cool! And since we now have the shadow picture, we might even tweak it
without that much issues.

One last thing - I apologize for the quality of some of my mails. I
don't know why, but I tend to reply to your posts at the end of my
(LibO) day ...
