Subject: Merged JSR-231 branch on to the main JOGL trunk. The main trunk now
 contains the evolving JSR-231 Reference Implementation and the JSR-231 branch
 is permanently closed.

+
+      <li> The passed component's bounds indicate the location of the
+      component on the desktop. The (x,y) of the bounds correspond to
+      the upper left of the component; note that this differs from the
+      OpenGL coordinate system.
+
+      <li> The <code>isAddition</code> parameter indicates whether
+      the component is being added to or removed from the desktop.
+
+      <li> The <code>oglViewportOfDesktop</code> specifies the
+      rectangle corresponding to the entire desktop pane in the
+      default OpenGL coordinate system with the (x, y) origin of the
+      rectangle at the lower left. This rectangle should be used in
+      conjunction with the component's bounds and the
+      <code>viewportOffsetFromOrigin</code> to determine where to draw
+      the vertices for the component.
+
+      <li> The <code>viewportOffsetFromOrigin</code> specifies the
+      current OpenGL viewport's offset from the origin of the OpenGL
+      coordinate system. The XTDesktopPane re-centers the OpenGL
+      viewport around each component so any perspective effects appear
+      symmetric. This offset should be subtracted from the translation
+      of the component or its vertex locations.
+
+      <li> The <code>oglTexCoordsOnBackBuffer</code> specifies the
+      texture coordinates of the passed component on the back
+      buffer. The (x,y) of this rectangle specifies the lower-left
+      corner of the image corresponding to the component. </ul>
