/**
* Instances of this class represent the "windows"
* which the desktop or "window manager" is managing.
* Instances that do not have a parent (that is, they
* are built using the constructor, which takes a
* <code>Display</code> as the argument) are described
* as <em>top level</em> shells. Instances that do have
* a parent are described as <em>secondary</em> or
* <em>dialog</em> shells.
* <p>
* Instances are always displayed in one of the maximized,
* minimized or normal states:
* <ul>
* <li>
* When an instance is marked as <em>maximized</em>, the
* window manager will typically resize it to fill the
* entire visible area of the display, and the instance
* is usually put in a state where it can not be resized
* (even if it has style <code>RESIZE</code>) until it is
* no longer maximized.
* </li><li>
* When an instance is in the <em>normal</em> state (neither
* maximized or minimized), its appearance is controlled by
* the style constants which were specified when it was created
* and the restrictions of the window manager (see below).
* </li><li>
* When an instance has been marked as <em>minimized</em>,
* its contents (client area) will usually not be visible,
* and depending on the window manager, it may be
* "iconified" (that is, replaced on the desktop by a small
* simplified representation of itself), relocated to a
* distinguished area of the screen, or hidden. Combinations
* of these changes are also possible.
* </li>
* </ul>
* </p><p>
* The <em>modality</em> of an instance may be specified using
* style bits. The modality style bits are used to determine
* whether input is blocked for other shells on the display.
* The <code>PRIMARY_MODAL</code> style allows an instance to block
* input to its parent. The <code>APPLICATION_MODAL</code> style
* allows an instance to block input to every other shell in the
* display. The <code>SYSTEM_MODAL</code> style allows an instance
* to block input to all shells, including shells belonging to
* different applications.
* </p><p>
* Note: The styles supported by this class are treated
* as <em>HINT</em>s, since the window manager for the
* desktop on which the instance is visible has ultimate
* control over the appearance and behavior of decorations
* and modality. For example, some window managers only
* support resizable windows and will always assume the
* RESIZE style, even if it is not set. In addition, if a
* modality style is not supported, it is "upgraded" to a
* more restrictive modality style that is supported. For
* example, if <code>PRIMARY_MODAL</code> is not supported,
* it would be upgraded to <code>APPLICATION_MODAL</code>.
* A modality style may also be "downgraded" to a less
* restrictive style. For example, most operating systems
* no longer support <code>SYSTEM_MODAL</code> because
* it can freeze up the desktop, so this is typically
* downgraded to <code>APPLICATION_MODAL</code>.
* <dl>
* <dt><b>Styles:</b></dt>
* <dd>BORDER, CLOSE, MIN, MAX, NO_TRIM, RESIZE, TITLE, ON_TOP, TOOL, SHEET</dd>
* <dd>APPLICATION_MODAL, MODELESS, PRIMARY_MODAL, SYSTEM_MODAL</dd>
* <dt><b>Events:</b></dt>
* <dd>Activate, Close, Deactivate, Deiconify, Iconify</dd>
* </dl>
* Class <code>SWT</code> provides two "convenience constants"
* for the most commonly required style combinations:
* <dl>
* <dt><code>SHELL_TRIM</code></dt>
* <dd>
* the result of combining the constants which are required
* to produce a typical application top level shell: (that
* is, <code>CLOSE | TITLE | MIN | MAX | RESIZE</code>)
* </dd>
* <dt><code>DIALOG_TRIM</code></dt>
* <dd>
* the result of combining the constants which are required
* to produce a typical application dialog shell: (that
* is, <code>TITLE | CLOSE | BORDER</code>)
* </dd>
* </dl>
* </p>
* <p>
* Note: Only one of the styles APPLICATION_MODAL, MODELESS,
* PRIMARY_MODAL and SYSTEM_MODAL may be specified.
