	* app/core/gimppickable.[ch]: added new methods ::get_bytes() and
	::flush()

	* app/core/gimpchannel.c
	* app/core/gimpdrawable.c
	* app/core/gimpimagemap.c
	* app/core/gimpprojection.c: implement ::get_bytes()

	* app/core/gimpprojection.c: implement ::flush() (immediately
	process both the idle renderer's queue and the unflushed update
	areas, to make sure that any reading from the projection will
	re-construct it).

	* app/core/gimp-edit.c
	* app/core/gimpchannel.c
	* app/core/gimpimage-contiguous-region.c
	* app/core/gimpimage-crop.c
	* app/core/gimppalette-import.c
	* app/paint/gimpclone.c
	* app/tools/gimpbycolorselecttool.c
	* app/tools/gimpiscissorstool.c
	* tools/pdbgen/pdb/image.pdb: use the pickable interface more
	consistently when reading from any drawable or the projection, and
	call gimp_pickable_flush() before doing so. Fixes bug #332933.

	* app/core/gimpimage-pick-color.c: added comment why the we don't
	call gimp_pickable_flush() here.

	* app/pdb/image_cmds.c
	* libgimp/gimpimage_pdb.c: regenerated.
