Got the basic highlight mechanism into place.

Tiles are getting rendered through a filter which works out where the target is in relation to the tile extents and draws a blob (currently a shadowed yellow rectangle) on the tile before streaming the image out as a png.

Uses the new javax.imageio package (well, new to me anyway).

It's really showing up the errors in our projection - near the equator the blob is too high, near the pole the blob is too low. I chose our constant so that London lines up, but it would be good to find out exactly what transformation was used for the map. Longitude is dead on.
