Issues involve:
- :layout() had the wrong signature and expected a cr argument that was left
from when this was still the :draw() function.
- horizontal and vertical reflection were mixed up (I guess it has always been
this way?)
- The return value should be a table of widget placements. Instead it was just a
single widget placement.
This is broken since commit 85ab3f045b.
