The original code was intended purely for rotation == 0
In cf70ba37 the condition was
changed to use it only for rotation != 0
which broke the cases for which it was intended to be used
as well as breaking cases for which it was not intended to be
used.
This changes the code so it could work for the more general
case and fixes the regressions
