The reason that a new/extended format is needed is that GEGL is more
general than a tree - it uses graphs. At the moment GEGL uses the
implicit tree of the nodes from XML + the ability to clone outputs to
represent the subset of graphs that are representable with sources,
filters and composers (two input pads, one output pad). All of the
programming API in GEGL deals with graphs not trees - the tree
representation of constrained subsets can however still be useful to
use both for _some_ deserialization purposes as well as UI
representations.
