00025 // Description : Another offscreen buffer in the GLX environment.  This
00026 //               creates a Pixmap object, which is probably less
00027 //               efficient than a GLXPBuffer, so this class is a
00028 //               second choice to glxGraphicsBuffer.  However, this
00029 //               might be the only option for some graphics drivers.
