	* app/core/gimpimage-mask-select.[ch]: changed
	gimp_image_mask_select_channel() to not take "drawable" and
	"sample_merged" parameters (which are silly in some contexts) but
	simply the offsets of the passed channel.

	* app/gui/channels-commands.c
	* app/tools/gimpbezierselecttool.c
	* app/tools/gimpfuzzyselecttool.c
	* app/tools/gimpiscissorstool.c: changed accordingly.

	* app/tools/gimpdrawtool.[ch]: chaged gimp_draw_tool_draw_lines()
	and _draw_strokes() to take an additional "use_offsets" parameter
	like the other drawing functions.

	* app/path_curves.c
	* app/tools/gimpvectortool.c: changed accordingly.

	* app/paint/gimppaintcore.c: removed #if 0'ed code which was
	identical to other functions.

	* app/tools/gimpselectiontool.c: use the GimpEditSelectionTool's
	"arrow_key_func" so it's now possible to keyboad-move the current
	layer and selection with all selection tool. Needs some more
	tweaking...

	* app/tools/gimpiscissorstool.[ch]
	* app/tools/gimpvectortool.[ch]: derive them from GimpSelectionTool
	to make the modifier key <-> tool options interaction work. Ported
	IScissors to the new way the draw_tool works.
