[etoys-dev] SQ-94 - Flip and Tumble

[Steve Thomas]

Okay read Bert's comment in Tracker and I now understand that the graphic is
flipped without changing heading (which differs from the implementation
using "rotation style" which by design changes heading to cause the flip).

So given that we want to have the minimum set of tiles from which you can
create things.  Why do we need both?
I understand the need to keep the older rotation style methods so older
projects don't break, but IMNSOBOWO we should hide the rotation style tile.
