Ok. here you have some effects. this is just an fast example. this is your file rasterized to 9000x9000 geoTiff in black&white and then converted to sqlitedb. I didnt make a Labels, but it is possible. there are some holes in the atlas on some zoom levels, but on the max zoom it should be the whole image. during the conversion, Mapc2Mapc told me: there is a limit of 5000 tiles :/
.shp ->(FME)-> geoTiff ->(Mapc2Mapc)-> Locus sqlitedb
.shp ->(FME)-> geoTiff ->(Mapc2Mapc)-> Locus sqlitedb
