Subject: [PATCH 003/109] fdo#61272: Do the mapping correctly both for WMF and
 EMF.

Turns out that for the WMF, we already had everything set up correctly, we
were just overwriting the right settings with default data again :-) - fix
that.

Includes the following commits:

* Revert "wmf-mm-text-1.diff: Fix WMF rendering, n#417818"
* Revert "wmf-mm-text.diff: Fix WMF rendering, n#417818"
* fdo#56886 EMF: Fixes some scaling problems of clipped regions, Twips
