feature request: more frames and delay for bg tile animations

[GregoryMcGregerson]

Not sure if this has been asked for in the past but the engine needs to have more options for animated bg tiles. From looking at the files of Zelda games the animations vary quite a bit. Some games have 3 frames others have 4 and one even has 8 frames! The delay on these are also different depending on the game. I've used sprites in the past to get around this but the engine doesn't load the sprite animation unless it's in view which is not always in sync with the rest of the sprites. It's pretty weird. Anyways I think this would be a nice feature to expand on.
