Archive based project storage with XML catalog

My toy GEGL which evolved into a video compositing end editing application also had a by product of a versatile proof of concept XML based project description [1]. Disregarding the temporal aspects of it, it is a structure that allows for layer groups, effect layers and cloned layers.

I attempted to condense it down somewhat and remove some of the mistakes in the initial implementation and tentativly called that XML structure XCF2[2].

One of the things that would remain for making this kind of format a standard is deciding upon baseline features to be implemented, and a baseline set of operations that need to be supported PNG, SVG, JPG, ICC and EXR might seem like some of the binary formats that are referenced by the catalog.

I'm not sure about jpeg, and a more flexible binary raster format would be needed, too, to support the colormodels png cannot support. And we'd need to have an authoritative list of composite ops and all that kind of thing.
