/**
* CommonGraphics2D class is a super class for all system-dependent
* implementations. It implements major part of Graphics and Graphics2D
* abstract methods.
* <h2>CommonGraphics2D Class Internals</h2>
* <h3>Line and Shape Rasterizers</h3>
* <p>
* The CommonGraphics2D class splits all shapes into a set of rectangles
* to unify the drawing process for different operating systems and architectures.
* For this purpose Java 2D* uses the JavaShapeRasterizer and the JavaLineRasterizer
* classes from the org.apache.harmony.awt.gl.render package. The JavaShapeRasterizer
* class splits an object implementing a Shape interface into a set of rectangles and
* produces a MultiRectArea object. The JavaLineRasterizer class makes line drawing
* more accurate and processes lines with strokes, which are instances of the BasicStroke
* class.
* </p>
* <p>
* To port the shape drawing to another platform you just need to override
* rectangle-drawing methods. However, if your operating system has functions to draw
* particular shapes, you can optimize your subclass of the CommonGraphics2D class by
* using this functionality in overridden methods.
* </p>
* <h3>Blitters</h3>
* <p>
* Blitter classes draw images on the display or buffered images. All blitters inherit
* the org.apache.harmony.awt.gl.render.Blitter interface.
* </p>
* <p>Blitters are divided into:
* <ul>
* <li>Native blitters for simple types of images, which the underlying native library
* can draw.</li>
* <li>Java* blitters for those types of images, which the underlying native library
* cannot handle.</li>
* </ul></p>
* <p>
* DRL Java 2D* also uses blitters to fill the shapes and the user-defined subclasses
* of the java.awt.Paint class with paints, which the system does not support.
* </p>
*
*<h3>Text Renderers</h3>
*<p>
*Text renderers draw strings and glyph vectors. All text renderers are subclasses
*of the org.apache.harmony.awt.gl.TextRenderer class.
*</p>
*
