95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	25 * A utility for coordinating figure animations. During animation, multiple
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	26 * <i>animators</i> are employed to capture the <em>initial</em> and <em>final</em> states
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	27 * for one or more figures. The animators then playback the animation by interpolating the
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	28 * intermediate states for each figure using the initial and final "keyframes".
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	29 * <P>
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	30 * An animator is usually stateless and represents an specific technique. Any state
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	31 * information is stored by the Animation utility. Therefore, one instance can be used
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	32 * with multiple figures. Animators hook into the validation mechanism for figures and
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	33 * connections. These hooks are used to capture the states, and to intercept the typical
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	34 * layout process to insert the interpolated state.
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	35 * <P>
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	36 * To indicate that animation is desired, clients must call {@link #markBegin()} prior to
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	37 * invalidating any figures that are to be included in the animation. After this method is
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	38 * called, changes are made, and {@link #run()} is invoked. The run method will force a
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	39 * validation pass to capture the final states, and then commence the animation. The
95307ad235d9 Added Draw2d code, still work in progress Frank Benoit <benoit@tionex.de> parents: diff changeset	40 * animation is synchronous and the method does not return until the animation has
