/**

 * <p>A component that includes a {@link MapContext MapContext} with support for use it as a particular {@link Behavior Behavior}.</p>

 *

 * <p>A developer can register a set of <code>Behavior</code>, but only one (that can be a composition of several) of them can be active. The active one

 *  defines the way to work and access with its <code>MapContext</code>'s layers. The active behavior, in combination with the appropriate

 *  {@link ToolListener ToolListener} will allow user work with a particular <i>tool</i>.</p>

 *

 * <p>All mouse events produced on this component will be delegated to the current active behavior, the <i>currentMapTool</i>.</p>

 *

 * <p><b>Drawing process:</b></p>

 *

 * <p>Uses a double buffer for the drawing process of <code>MapContext</code>'s information.</p>

 *

 * <p>If the double buffer wasn't created, creates a new one.</p>

 *

 * <p>Paints the component according the following algorithm:

 * <br>

 *  &nbsp If <i>status</i> is <i>UPDATED</i>:<br>

 *  &nbsp &nbsp If there is a <i>double buffer</i>:<br>

 *  &nbsp &nbsp &nbsp If there is a <i>behavior</i> for managing the <code>MapControl</code> instance, delegates

 *   the drawing process to that behavior, calling: <code><i>behavior_instance</i>.paintComponent(g)</code>.<br>

 *  &nbsp &nbsp &nbsp Else, repaints the current graphical information quickly calling: <code>g.drawImage(image,0,0,null)</code>.<br>

 *  &nbsp Else, (<i>status</i> is <i>OUTDATED</i>, or <i>ONLY_GRAPHICS</i>): executes a quickly repaint of the previous information calling <code>g.drawImage(image,0,0,null)</code>, and creates

 *   a <i>painting request</i> to delegate the heavy drawing process to the {@link Drawer2 Drawer2}'s worker thread, according the <i>SingleWorketThread</i> pattern, starting a timer to update

 *   (invoking <code>repaint()</code>) the view every delay of <code>1000 / drawFrameRate</code> ms. during that heavy drawing process, and if its enabled <code>drawAnimationEnabled</code>. The <i>painting request</i> once is being attended, invokes <code>MapContext</code> to

 *   draw the layers: <code>mapContext.draw(image, g, cancel,mapContext.getScaleView());</code>

 * <br>

 * <p>Some notes:

 *  <ul>

 *   <li>The painting process can be cancelled calling {@link #cancelDrawing() #cancelDrawing()}.</li>

 *   <li>At last resort, the particular implementation of each layer in a <code>MapControl</code>'s <code>MapContrext</code>

 *    will be that one which will draw the graphical information, and, if supports, which could cancel its drawing subprocess.</li>

 *   <li>It's possible to force repaint all layers, calling {@link #drawMap(boolean doClear) #drawMap(boolean)}.</li>

 *   <li>It's possible repaint only the dirty layers, calling {@link #rePaintDirtyLayers() #rePaintDirtyLayers()}.</li>

 *   <li>It's possible repaint only the {@link GraphicLayer GraphicLayer}, calling {@link #drawGraphics() #drawGraphics()}.</li>

 *  </ul>

 * </p>

 *

 * <p><b>Tools:</b></p>

 *

 * <p>A developer can:

 *   <ul>

 *    <li>Register each tool as:

 *     <ul>

 *      <li>A single behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>

 *      <li>Or, a compound behavior: {@link #addMapTool(String, Behavior) #addMapTool(String, Behavior)}.</li>

 *     </ul>

 *    </li>

 *    <li>Get the current active tool: {@link #getCurrentMapTool() #getCurrentMapTool()}.</li>

 *    <li>Get the current active tool name: {@link #getCurrentTool() #getCurrentTool()}.</li>

 *    <li>Get a registered tool: {@link #getMapTool(String) #getMapTool(String)}.</li>

 *    <li>Get the name of all tools registered: {@link #getMapToolsKeySet() #getMapToolsKeySet()}.</li>

 *    <li>Get all tools registered, including the name they were registered: {@link #getNamesMapTools() #getNamesMapTools()}.</li>

 *    <li>Determine if has a tool registered: {@link #hasTool(String) #hasTool(String)}.</li>

 *    <li>Set as an active tool, one of the registered: {@link #setTool(String) #setTool(String)}.</li>

 *    <li>Set as active tool, the previous used: {@link #setPrevTool() #setPrevTool()}.</li>

 *    <li>Set the current tool: {@link #setCurrentMapTool(Behavior) #setCurrentMapTool(Behavior)}.</li>

 *    <li>Change the draw frame rate: {@link #setDrawFrameRate(int) #setDrawFrameRate(int)} and {@link #applyFrameRate() #applyFrameRate()}.</li>

 *    <li>Get the draw frame rate: {@link #getDrawFrameRate() #getDrawFrameRate()}.</li>

 *    <li>Determine if will repaint this component each time timer finishes: {@link #isDrawAnimationEnabled() #isDrawAnimationEnabled()}.</li>

 *    <li>Change if will repaint this component each time timer finishes: {@link #setDrawAnimationEnabled(boolean) #setDrawAnimationEnabled(boolean)}.</li>

 *    <li>Get the shared object that determines if a drawing process must be cancelled or can continue: {@link #getCanceldraw() #getCanceldraw()}.</li>

 *    <li>Get the combined tool: {@link #getCombinedTool() #getCombinedTool()}.</li>

 *    <li>Set a combined tool: {@link #setCombinedTool(Behavior) #setCombinedTool(Behavior)}.</li>

 *    <li>Remove the combined tool: {@link #removeCombinedTool() #removeCombinedTool()}.</li>

 *   </ul>

 * </p>

 *

 * <p><b>Exception listener:</b></p>

 *

 * <p> Adding an <code>ExceptionListener</code>, can get notification about any exception produced:

 *  <ul>

 *   <li>Attending a <i>painting request</i>.</li>

 *   <li>Working with the active tool.</li>

 *   <li>Applying a <i>zoom in</i> or <i>zoom out</i> operation.</li>

 *  </ul>

 * </p>

 *

 * <p><b>Other:</b></p>

 *

 * <p>Other useful capabilities of <code>MapControl</code>:

 *   <ul>

 *    <li>Cancel the current drawing process (notifying it also to the inner

 *     <code>MapContext</code> instance and its layers): {@link #cancelDrawing() #cancelDrawing()}.</li>

 *    <li>Applying a <i>zoom in</i> operation centered at mouse position (without a <code>ToolListener</code>): {@link #zoomIn() #zoomIn()}.</li>

 *    <li>Applying a <i>zoom out</i> operation centered at mouse position (without a <code>ToolListener</code>): {@link #zoomOut() #zoomOut()}.</li>

 *   </ul>
