Fix negative font rendering on Mac by reversing matrix c component.

Fix negative font rendering on Mac by reversing matrix c component.

Notice that this is just making it analoguous to how it works when the
font is positive: the b and d components are reversed. Currently, when
the font is negative, only the a component is reversed. The c one needs
to be reversed as well.
