There's need for manually calling swapBuffers() for things like rendering progress 
bars while defining textures or building complex display lists.

This functionality has been added. The primary reason for doing so was not the
reason submitted, but because some applications need to draw the scene into the
back buffer without displaying it in order to implement picking functionality.
This was inconvenient or impossible to do without manual control over the
swapping of the front and back buffers.

The following three methods have been added to GLDrawable:
  public void setAutoSwapBufferMode(boolean onOrOff);
  public boolean getAutoSwapBufferMode();
  public void swapBuffers();

Tested with the ProceduralTexturePhysics demo. Currently there aren't any JOGL
demos checked in which illustrate the use of these APIs.
