This commit fixes radiosity to correctly preserve and subdivide UV
coordinates.

Known problem: Pin status bleeds a bit, so new subdivided UVs around
points that were original pinned can end up pinned in the end. Could be
fixed, or could just drop pinned status entirely.

Also, when gathering meshes, it doesn't add materials twice, so it's harder to bust the 16 materials limit.
