Remap: Loop raycasting: fallback to nearest check in case raycasting fails.

Reason is, it's usually really bad to have most loops of a dest face to map
correctly to a source island, and one or two mapping to nothing because raycasting
went outside of the island's geometry.

Also, in raycast/nearest queries, systematically do a copy of given co/no,
we do nor loose much, and inplace modifications here was getting way too
much confusing (easy to generate bugs this way, e.g. with 'refinement'
process of raycasting, co/no ended up getting transformed several times!).
