[Talk-GB] Mapping buildings with gables

[andrew]

Many houses in the London suburbs and elsewhere have polygonal or curved bays
with square-ended gables above them. A typical example is:

Should we be mapping the outline of the gable because it is the greatest extent
of the building, the bay because it is the important bit or a straight line
because the bay and gable are too small to map sensibly?
