The idea behind this concept was to be able to mmap the tiles directly from the file although this part has never been implemented. And there is a whole lot more to XCF than layers ... I'd suggest you use a more standardized animation format such as MNG. XCF is not meant to be used by anything but The GIMP. It's not documented and we usually discourage people from using it. One of the reasons is that it makes it easier for us to change the format without taking the risk of breaking lots of third-party applications. For GIMP-2.0 we might try to design a file format that is better suited as an inter-application exchange format. We've already spent some thought on this and it might even happen one day.
