Scale does not work as expected.

Commenting post 1: Scale does not work as expected. For example try to put in negative parameters. This should in case of -1.0 just mirror the part. -1.0 in X does nothing. -1.0 in Y changes x and y coordinates. Negative numbers for scaling should be usable for the purpose of mirror tranformations in python scripting. I tried at with freecad 0.13git1904
