InitFont() is always called after ImplNewFont(). Calling
InitFont() without a call to ImplNewFont() doesn't make much
sense.

There are some places which don't need to set the SalGraphics
font, but these are fine with calling ImplNewFont() as is.

It now looks like Printer' and OutputDevice' InitFont() do the
same, after commit c766a05a ("Antialias drawing is part of
the font selection") moved Antialias handling into the common
ImplNewFont() function.
