This change uses 2 interleaving OpenGL PixelBufferObjects for readback instead of syncing CPU to GPU all the time.
I've also incorporated here changes proposed by @ftlPhysicsGuy ( here: #121)
Additional improvement would be to not fill any intermediary structures and fill writeable image directly (as we are not using framebuffer of hidden window!)
