	* app/display/gimpdisplayshell-callbacks.c: use
	gimp_display_shell_[install|remove]_override_cursor() to set the
	middle mouse button move cursor so we get the original cursor back
	after scrolling.

	* app/tools/gimpdrawtool.[ch]: added lots of drawing functions
	(gimp_draw_tool_draw_rectangle() etc.) which work in image (or
	active drawable) coordinates.

	* app/tools/gimpblendtool.c
	* app/tools/gimpclonetool.c
	* app/tools/gimpcolorpickertool.c
	* app/tools/gimpeditselectiontool.c
	* app/tools/gimpellipseselecttool.c
	* app/tools/gimpfreeselecttool.c
	* app/tools/gimpiscissorstool.c
	* app/tools/gimpmagnifytool.c
	* app/tools/gimpmeasuretool.c
	* app/tools/gimppainttool.c
	* app/tools/gimppathtool.c
	* app/tools/gimprectselecttool.c
	* app/tools/gimptransformtool.[ch]
	* app/tools/path_tool.[ch]: use the new functions. Removed tons of
	gdk_draw_foo() and gdisplay_transform_foo() calls. Most drawing
	functions look *much* nicer now. Ported some tools to detect
	handle clicks in display coordinates while I was on it, misc
	fixes.

	* app/tools/gimpmovetool.[ch]: derive from GimpDrawTool instead
	of drawing manually.
