tdf#55058 tdf#143875 EMF+ Don't change line weight while rotating

Previously when TranfromationMatrix was used with rotation,
the line weight and dashed line shapes were changed.
In worst case if angle was larger than 90 degrees,
the lines just disappear.

This patch fixes that. The line looks exactly after rotation
(with TranfromationMatrix).

The tests were updated (added some additional rotation),
to prove that now it is working correctly.
