# What does each build draw in the out-of-range BAR box?

# The provoke mask localised the offending block to a 13x52 rectangle.  The
# question that decides whether the fix cures the operator's yellow bar is
# simply: in the SEC (colour) plane, does the shipped binary light those
# pixels, and do we?
