 * @brief Main view to display and control the remote computer.
 *
 * This view class handles everything related to showing the remote display
 * and interacting with it. It is tightly coupled with the RFBConnection
 * instance and is its delegate. The actual drawing of the framebuffer
 * is done by the VNCContentView that the child of the scroller view.
 * A number of method invocations are forwarded to the content
 * view rather than be implemented directly by this class.
 *
 * The view hierarchy looks like this:
 * 
 *		VNCView -> VNCScrollerView -> VNCContentView
 *
