GimpOperationLayerMode instantiable and add a GimpLayerModeEffects
property to it that we check in ::process() to blend pixels
together.
* app/gegl/gimpoperationlayermode.[ch]: Do the change described
above. Currently only Normal and Addition are implemented. Normal
so that we don't need a special case for the gegl:normal op. Also,
the Dissolve layer mode is not a point op and needs to be
implemented elsewhere.
* app/gegl/gimpoperation*mode.c: Removed.
* app/gegl/gimp-gegl-utils.[ch]: Removed
gimp_layer_mode_to_gegl_operation().
* app/core/gimplayer.c
* app/gegl/Makefile.am
* app/gegl/gimp-gegl.c: Adapt.

* app/gegl/gimpoperationpointcomposer.[ch]: renamed this class...
* app/gegl/gimpoperationlayermode.[ch]: ...to this and add
an own process() virtual function so we are free to hack even
more badly in order to support legacy layer modes and proper
ones which do meningfiul things to alpha. Simply redirect
GeglOperationPointComposer's compose() calls to our own vfunc
for now.
* app/gegl/gegl-types.h
* app/gegl/Makefile.am: changed accordingly.
* app/gegl/gimpoperation*mode.[ch]: changed parent class and
implemented process() method accordingly.

* app/gegl/gimpoperationpointcomposer.[ch]: add an empty abstract
GeglOperationPointComposer subclass which can be used to hook in
common debug or test or whatever code for below layer modes.
* app/gegl/gimpoperation*mode.[ch]: add empty stubs of layer mode
operations which do nothing but copying input to output.
* app/gegl/Makefile.am
* app/gegl/gegl-types.h: add them here and reordered things a bit.
* app/gegl/gimp-gegl.c (gimp_gegl_init): register the new
operations.
* app/gegl/gimp-gegl-utils.c (gimp_layer_mode_to_gegl_operation):
return the new operations.
