Gui_NewGame.java improvements for Macs
`Peered AWT components, such as Label and TextField, can only use logical fonts.
Logical fonts are the five font families defined by the Java platform which must be supported by any Java runtime environment: Serif, SansSerif, Monospaced, Dialog, and DialogInput. These logical fonts are not actual font libraries. Instead, the logical font names are mapped to physical fonts by the Java runtime environment. The mapping is implementation and usually locale dependent, so the look and the metrics provided by them vary. Typically, each logical font name maps to several physical fonts in order to cover a large range of characters.
The Dialog font used on Apple Macintosh computer's OS X have a thicker pen stroke and take up a wee bit more space than what we see on Windows computers. I have no idea how these logical fonts look on *nix systems.
I made some changes to the Gui_NewGame.java file and the New Game window now looks acceptable on my Mac.
