The warping between OSGB36 (EPSG: 27700) and EPSG: '900913'.

Richard's tiles use a custom conversion script with antialiasing on
the resample. Edgemaster's tile used gdal2tiles.

I'm working on some cleaned up and pngcrush'ed tiles, but do not
expect them in the next few days. The existing tiles are more than
good enough.
