/**
* Specifies a Swing-coordinates camera, suitable for mixing with Swing and
* the 2D scene graph. The coordinate system defined by this camera has its
* origin in the upper left corner of the panel with the Y-axis pointing
* down and the Z axis pointing away from the viewer (into the screen). The
* units are in pixel coordinates at the projection plane (Z=0),
* regardless of the size of the panel.
* The viewing transform is defined by specifying the zero point, the viewing
* direction, and the up vector.
* This resulting transform is used as the view portion of the ModelView matrix.
* The projection transform a fixed perspective transform. The 3D viewport is
* set to the bounds of the panel.
