+* This class provides access to a small number of DWT system-wide

+* by DWT.
+* <p>
+* By defining constants like UP and DOWN in a single class, DWT
+* can share common names and concepts at the same time minimizing
+* the number of classes, names and constants for the application
+* programmer.
+* </p><p>
+* Note that some of the constants provided by this class represent
+* optional, appearance related aspects of widgets which are available
+* either only on some window systems, or for a differing set of
+* widgets on each window system. These constants are marked
+* as <em>HINT</em>s. The set of widgets which support a particular
+* <em>HINT</em> may change from release to release, although we typically
+* will not withdraw support for a <em>HINT</em> once it is made available.
+* </p>
