The origin is the tile origins texel coordinate within the larger
texture, the filetile is the number of the tile typically used for
naming the file.

For example, a 2kx2k image with 512x512 tiles might have an origin of
1025,512, that could correspond to a filetile of 2,1, i.e. 2 tiles in
and 1 tile up relative to the 0,0 tile.

Cheers,ANgus.
