Improve var-width miter joins
With variable width stroke, there is a curious case where both sides
need an inner or an outer join, instead of the fixed width case where
each side will have opposite join types. This improves the miter join
logic to treat the "left" and "right" sides separately.
There is still work to be done for joins, it's still too easy to create
weirdness.
Also improved debugging messages for degenerate cases instead of
silently swallowing the errors.
