* This class implements permissions for AWT. This is a named

* permission names with a description of what that permission allows.<br>
* <table border=1>
* <tr><th>Permission Name</th><th>Permission Allows</th><th>Risks</th</tr>
* <tr>
* <td><code>accessClipboard</code></td>
* <td>posting and reading the AWT clipboard</td>
* <td>the clipboard may contain sensitive data</td></tr>
* <tr>
* <td><code>accessEventQueue</code></td>
* <td>access to the AWT event queue</td>
* <td>malicious code could remove real events and replace them with bogus
* ones, including simulating the user granting permission</td></tr>
* <tr>
* <td><code>listenToAllAWTEvents</code></td>
* <td>listen to system-wide AWT events</td>
* <td>malicious code can read passwords entered in an AWT event, and in
* combination with accessEventQueue, could fake system events</td></tr>
* <tr>
* <td><code>showWindowWithoutWarningBanner</code></td>
* <td>display a window without a banner notification of insecurity</td>
* <td>malicious code could install a Trojan horse applet that looks like
* a normal window, and thus steal data like passwords</td></tr>
* <tr>
* <td><code>readDisplayPixels</code></td>
* <td>read back pixels from the display screen</td>
* <td>malicious code could snoop on the user's actions</td></tr>
* <tr>
* <td><code>createRobot</code></td>
* <td>create an instance of java.awt.Robot</td>
* <td>these objects can generate events as though they were the user; so
* malicious code could control the system</td></tr>
* <tr>
* <td><code>fullScreenExclusive</code></td>
* <td>enter full-screen exclusive mode</td>
* <td>malicious code could masquerade as a trusted program</td></tr>
