+ * The BasicStroke class specifies a set of rendering attributes for the
+ * outlines of graphics primitives. The BasicStroke attributes describe the
+ * shape of the pen which draws the outline of a Shape and the decorations
+ * applied at the ends and joins of path segments of the Shape. The BasicStroke
+ * has the following rendering attributes:
+ * <p>
+ * <ul>
+ * <li>line width -the pen width which draws the outlines.</li>
+ * <li>end caps - indicates the decoration applied to the ends of unclosed
+ * subpaths and dash segments. The BasicStroke defines three different
+ * decorations: CAP_BUTT, CAP_ROUND, and CAP_SQUARE.</li>
+ * <li>line joins - indicates the decoration applied at the intersection of two
+ * path segments and at the intersection of the endpoints of a subpath. The
+ * BasicStroke defines three decorations: JOIN_BEVEL, JOIN_MITER, and
+ * JOIN_ROUND.</li>
+ * <li>miter limit - the limit to trim a line join that has a JOIN_MITER
+ * decoration.</li>
+ * <li>dash attributes - the definition of how to make a dash pattern by
+ * alternating between opaque and transparent sections</li>
+ * </ul>

+/**
+ * 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>
