Implementation note: all layer modes are implemented as GEGL
operations. The list can be found at:
app/operations/layer-modes/gimp-layer-modes.c
The "op_name" value in particular gives the operation name allowing
reader developers to search for this string. For instance, the
"Normal" layer mode is implemented as the "gimp:normal" GEGL operation
whose implementation can be found at:
app/operations/layer-modes/gimpoperationnormal.c
NOTE: The layer modes 'Old broken Overlay' and 'Soft light (legacy)' are identical.
