Oh interesting topic! To decide for a good "composition rendering strategy" I would suggest to take a look at some verry similar applications like motion compositig software. This type of software is used to do non destructive image editing to motion picture sequences in a way like GEGL

The spec is here: http://gui.gimp.org/index.php/Save_%2B_export_specification#exporting_files Quick version: The default export path needs a settings switch for whether the original file path (number 3) is higher-priority than the most-recently-used paths (numbers 1 and 2). This would support
