	* app/core/gimpchannel.[ch]: add a projection node and
	implement GimpDrawable::get_node(). Reconfigure the node in
	visibility_changed(), set_color(), set_opacity() and
	set_show_masked().

	* app/core/gimpimage.c (gimp_image_get_graph): enable code that
	projects the channels stack on top of the layer stack.

	* app/core/gimpprojection-construct.c: remove the call to
	gimp_projection_construct_channels() from the GEGL code path. Also
	don't touch proj->construct_flag.
