[PySide] conforming fonts between platforms

[anatoly techtonik]

>From my own experience with playing with TTF fonts on Windows (the
experiment is made with pyglet and checked into its codebase, so it
may be pyglet bug), there is no guarantee that all symbols in
monospace font have the same pixel size. It may disrupt layout easily.
So this setPixelSize looks like the stuff that allows to force proper
dimensions, and it is the only logical way to do for me.
