Render overlay tiles that were output by the compute pipeline.
We could determine the set of tiles with an overlay on CPU side by intersecting tile-ids to render with tile-ids requested from the compute pipeline. However, we are aiming to directly check for available of an overlay texture for a tile-id on the GPU, which should be possible after https://github.com/weBIGeo/webigeo/issues/18 is implemented.
