Any rotated text in an emf image (image size != original size),
has thicker fonts.
This is kind of a regression caused by commit
8c2902ecbf135fae070ea032fa10a59bb76ec1b0
So, partially reverted it.
The code was kind of a workaround/copy-paste, so I am assuming
it is safe to revert.
Side-effects: The dotted borders (in calc) look a
little lighter and not so very visible in the page-preview.
