You're right, of course. I knew I should have double-checked outside my game
code. Sorry for wasting your time. However, I think there is still room for a
doc patch. My confusion stemmed from thinking the sprite is rotated before it's
flipped and not vice versa. If you get this wrong, itofix(64) and itofix(192)
will give results as you would expect from a mythical rotate_sprite_h_flip().

Kind regards,
