  Serialize d/s buffers + use color buffers' impl format for readPixels
  
  Adds serialization of depth/stencil buffer contents
  
  Currently, readPixels on color buffers uses the gles front-end format,
  which can be different from the implementation format used in the
  backend. This can cause seg fault crashes when the number of bytes in
  a pixel differs between the two format. Changes so that readPixels for
  color buffers always use the backend format.
