        <p>Added new methods to class WinsysInfoForTabbedContainer to find out the

        status (enabled/disabled) of some window system features. For example, is the TopComponent

        allowed to slide-out.

    <description>

	<p>There is a set of new boolean client properties which platform

        developers can use to customize the behavior of individual TopComponents in NetBeans' window system:</p>

        <ul>

            <li>Disable window closing</li>

            <li>Disable window drag and drop</li>

            <li>Disable window undocking (floating windows)</li>

            <li>Disable window sliding</li>

            <li>Disable window maximization</li>

        </ul>

        <p>The features above can be turned on/off simply by branding of core.windows module.</p>
