tdf#121486: Correct scale of broken fonts on Windows
Some fonts have negative tmAveCharWidth which makes no sense (fonts can't have negative glyph width, so the average can't be negative) and it would cause our code to apply negative scale to the glyphs of these fonts making them drawn on the flipped horizontally. Fix this by using the absolute value so it is always positive.
