Michael Natterer bc8d5f84d6 app: remove the "offset" API from TileManager 
It made the transform code hard to read and never belonged into the
tile manager anyway. It's a simple pixel buffer that should not know
about any position in an image. Instead, pass around the offsets of
tile managers explicitly, so everything is less obscure for the price
of having more parameters. This will also help replacing TileManagers
with GeglBuffers.
