I've been thinking for a while that a tiling mode in the Sprite object would cover all of this, since it already supports custom origins and animations, and means that doesn't need to be reinvented for the Tiled Background. It would however make Tiled Background kind of a redundant object which could be deprecated, but then this is a pretty significant change to a core object which is used in all sorts of videos, tutorials, descriptions etc. all over our own site, manual, and the rest of the web. I'm not sure what to do about this - perhaps we could add a tiling mode to Sprite and keep a somewhat redundant Tiled Background just because lots of people will still expect it to be there?
