TextPreRotateAngle vs. TextRotateAngle

[Regina Henschel]

Hi all,

commit 
https://cgit.freedesktop.org/libreoffice/core/commit/?id=5c4d1b05faa8a3d704fc74a186a173f8cc019cc1

has introduced the TextPreRotateAngle. As far as I understand it, it has 
been introduced to express the rotation, which is applied to the 
TextFrames inside a custom shape and which is independent of the 
rotation applied to the shape itself. But that is exactly the purpose of 
TextRotateAngle. So why a second attribute?


The commit message is
n#734734: Text rotation fixes.

I have no access to that bugtracker. Can please someone who has access 
tell me, what it is about, and perhaps provide an anonymised version of 
a document attached to the bug if any?

Kind regards
Regina
