grafx - Extensible Java Graphics Package Code

Converting SimpleDemo in package com.nerius.grafx.d2.demo to use FrameAWTStub.
This is no longer a java.applet.Applet. It now has a main() method.

Creating a zero-arg FrameAWTStub constructor.

Removing TestFontFactory which is mostly dead code.

Moving DrawTextGeneral.java to DrawTextGeneral.java_, so that it isn't
compiled. Trying to minimize the use of java.applet.Applet.

Removing class 'AppletInFrame'.

Removing extra whitespace in LaunchLevelPlayback.

Making some progress on AppletInFrame, but realizing that this project will
probably have to be abandoned. For example, when the applet calls repaint(),
there nothing to react to it unless it's all hooked up.

Adding beginnings of class AppletInFrame. Not done yet.

Adding check to constructor of RasterDepthGraphics to ensure that both width
and height are strictly greater than zero.

Adding some Javadoc to RasterDepthGraphics which states that exception is
thrown when unimplemented method is called.
