	* tools/pdbgen/pdb/color.pdb (levels, curves): fiddle with the
	passed channel index only for GRAYA drawables, not for all GRAY
	drawables. Fixes bug #132322.

	* tools/pdbgen/pdb/color.pdb: regenerated.

	* app/tools/gimpcurvestool.[ch]
	* app/tools/gimplevelstool.[ch]: fixed the same bug here. It never
	occured because the "channel" field was accidentially initialized
	with the correct value and never changed after.
