avoid setting background as tiles

[kakaroto]

If we find a graphics that doesn't match 100% but matches, let's say 95% of the size and is the only one that meets the criteria, then set it as background with a position shift. Might be a bit tricky if the size doesn't match though, would need work through that somehow.

No, please leave them as tiles - it is much more flexible.

Yeah, it's more flexible, but I know Atropos said that there is a reason/advantage to having them as the actual background.. I can't remember what it was, but regardless, one issue I have is that selecting a tile brings it to the front, so when your background is a tile, it makes things really difficult to work with sometimes. Regardless of that, I understand your preference and I'll just make a --background-as-tile option for those who prefer them all to be tiles.
