The OpenGL version of Java 3D uses pBuffers for off-screen rendering.
Most drivers/cards do not accelerate this, but the whole reason this
feature was added to OpenGL is so that it could take advantage of
hardware rendering. We hope that more cards will start accelerating
this, but it will still be limited by the amount of available
off-screen memory on any particular card (e.g., a 3000x2000 pixel
off-screen buffer for printing is not likely to be accelerated any time
soon).
