Honor scale factor when sizing AWT frame.
Revamped text rendering based on NWO.

TextConfig is out, and TextStyle and StyledText are in. This also lays the
ground work for rendering "rich" text (once we get a smidgen more support from
PlayN). TextStyle will define the style of a span of text, and StyledText will
have one more create() method which takes an array of strings and styles which
will be wrapped into a specified wrap width.
Updated to use TextStyle and StyledText.
