* A Color class which adds the notion of alpha.
* Because DVBColor extends Color the signatures in the existing classes do not change. Classes
* like Component should work with DVBColor internally. Instances of this class are a
* container for the values which are passed in to the constructor. Any
* approximations made by the platform are made when the colors are used.
*
* Note: org.dvb.ui.DVBColor adds support for alpha (compared to JDK1.1.8) and is intended
* to be compatible with the JDK1.2 java.awt.Color class - since org.dvb.ui.DVBColor
* extends javax.tv.graphics.AlphaColor which in turn extends java.awt.Color. In
* implementations where java.awt.Color supports alpha, such as JDK1.2, etc., the
* alpha-related methods in org.dvb.ui.DVBColor could just call super.
