/**
 * <p>An NSWindow instance represents a window, panel or menu on the
 * screen.<br />
 * Each window has a style, which determines how the window is decorated:
 * ie whether it has a border, a title bar, a resize bar, minimise and
 * close buttons.
 * </p>
 * <p>A window has a <em>frame</em>. This is the frame of the <em>entire</em>
 * window on the screen, including all decorations and borders.  The origin
 * of the frame represents its bottom left corner and the frame is expressed
 * in screen coordinates (see [NSScreen]).
 * </p>
 * <p>When a window is created, it has a <em>private</em> [NSView] instance
 * which fills the entire window frame and whose coordinate system is the
 * same as the base coordinate system of the window (ie zero x and
 * y coordinates are at the bottom left corner of the window, with increasing
 * x and y corresponding to points to the right and above the origin).<br />
 * This view may be used by the library internals (and theme engines) to
 * draw window decorations if the backend library is not handling the
 * window decorations.
 * </p>
 * <p>A window always contains a <em>content view</em> which is the highest
 * level view available for public (application) use.  This view fills the
 * area of the window inside any decoration/border.<br />
 * This is the only part of the window that application programmers are
 * allowed to draw in directly.
 * </p>
 * <p>You can convert between view coordinates and window base coordinates
 * using the [NSView-convertPoint:fromView:], [NSView-convertPoint:toView:],
 * [NSView-convertRect:fromView:], and [NSView-convertRect:toView:]
 * methods with a nil view argument.<br />
 * You can convert between window and screen coordinates using the
 * -convertBaseToScreen: and -convertScreenToBase: methods.
 * </p>
