LayerData::prevState is now called fPreviousState and is now private. Added new method

PopState() to make this possible.
When a new layer is created, the font state of the desktop will now be set: this fixes
a bug I introduced when separating the font manager's default font and the desktop's
default font.
The scaling stuff looks pretty broken to me.
