* gegl/graph/gegl-node-context.c: added some extra debug output for
missing formats on pads (to be ignored for some core ops for now, but
gives better guidance when things crash.)
* gegl/operation/gegl-operation-composer.[ch]
* gegl/operation/gegl-operation-filter.[ch]:
* gegl/operation/gegl-operation-sink.[ch]:
* gegl/operation/gegl-operation-source.[ch]: added the buffers being
read from/written to as arguments of the process functions in the base
classes for the common operation types.
The rest of the files modified were modifications to update to never
API.
