/** Create a new transition for the given component.
<ul>
<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>
