Faulty handle position in shapes imported from MS Office (continued)

[Regina Henschel]

Hi all,

I have mentioned in the previous thread, that I'll make a proposal, so 
that discussing a solution is easier. For my first ideas, see now 
https://gerrit.libreoffice.org/70689.

Please take a look at the proposal.
Is the way suitable in principle? I am so indecisive, because both 
"enum" and "map" and thus the "switch" become quite big when all 
ooxml-foo shapes are captured. In addition, the inverting of the 
formulas is complex.
If this is the right way, it remains to be clarified where the parts 
should be placed.

Kind regards
Regina
