The scrolling features required revisions to both the MCU (since if you
are not word-aligned you need to send (at least) one more set of words
to the shifter per line) and the Shifter (so it could decide which pixel
of the word to start on).

Neither the STe shifter nor the new combined MCU/Glue can be directly
plugged into an ST.
