[Tagging] bridge movable vs swing vs swinging

[John Packer]

Richard,
Perhaps these cases in which the outline of the bridge was drawn is related
to this proposal:
http://wiki.openstreetmap.org/wiki/Proposed_features/man_made%3Dbridge

I believe it's main purpose is to solve a known rendering problem in
bridges.
Nowadays, when two or more parallel ways are in a bridge/viaduct, they are
drawn as separate bridges.
Drawing the area of the bridge would solve that.

Cheers,
John
