	* app/core/gimpimage.[ch]: renamed
	gimp_image_coords_in_active_drawable() to
	gimp_image_coords_in_active_pickable() and added boolean
	"sample_merged" and "selected_only" parameters. Use floor()
	instead of ROUND(), we want to round to the actual pixel, not to
	the nearest pixel boundary.

	* app/tools/gimpbucketfilltool.c
	* app/tools/gimpclonetool.c
	* app/tools/gimpcolortool.c
	* app/tools/gimpfliptool.c
	* app/tools/gimptransformtool.c: changed accordingly. Removed
	quite some duplicated code which checked sample_merged and the
	mask value at the cursor location.

	* app/tools/gimpbycolorselecttool.c: use the hand tool cursor,
	there's also a hand in the toolbox icon. Fixed cursor_update()
	function to set the bad modifier when there is no pickable pixel
	at the cursor loction.

	* app/tools/gimpfuzzyselecttool.c: added cursor_update()
	implementation which does the same as by_color_select's one.

	* app/tools/gimpselectiontool.c
	(gimp_selection_tool_cursor_update): don't override the bad
	modifier which was set by a subclass' cursor_update().
