  *  For easier compatibility with Skia's GPU backend, we further restrict these
  *  to either (in memory-byte-order) RGBA or BGRA. Note that this "order" does
  *  not directly correspond to the same shift-order, since we have to take endianess
  *  into account.

  *  Here we enforce this constraint.
