GeglOperation
* operation names are now prefixed, the ops in GEGL use 'gegl:' as prefix.

* gegl:src-in - deal correctly with extens.
* gegl:path - new op covering the stroke/fill needs of SVG.
* deprecated gegl:shift, the affine familiy of operations now
uses the same fast code paths for integer translations.
GeglBuffer
* Profiling motivated speed ups in data reading/writing.
* Remove left-over swapfiles from dead processes at startup.
GeglNode
* made gegl_node_add_child and gegl_node_remove_child public API.
GeglPath
* Vector path representation infrastructure, supporting poly lines and beziers
by default, the infrastructure allows extensions from applications with
other curve types (smooth curves, spiro curves and others.).
framework.
GEGL provides infrastructure to do demand based cached non destructive
image editing on larger than RAM buffers. Through babl it provides
support for a wide range of color models and pixel storage formats for
