Support all the crazy different pixel store unpack parameters

Browse Source 
* If the pixel store parameters are relatively simple we go through a
  fast path that's about the same as it was before, otherwise we manually
  unpack to a tightly packed buffer for serialising. Hopefully this should
  rarely happen.
* glPixelStore parameters are only serialised when capturing a frame, and
  the pixel store parameters at frame start form part of the initial state
  vector.
