For each frame {
1 longlong = 4 bytes
          offset to data (probably only used internally by STOS)
1 byte          width in words (multiply by 16 to get width in pixels)
1 byte          height in pixels
1 byte          X hotspot location
1 byte          Y hotspot location
}

(The format implies other stuff could be here.)

?               words of data for each frame, in the order mentioned in the
                header.  Monoplanar mask data follows image data for each
                frame.
? words         total

  The frames often seem to be in semi-random order, not necessarily
in the order they are to be animated.
