Michael Natterer d51c50820f Bug 496772 – Position shown in the statusbar needs more precision (for 
2008-08-20  Michael Natterer  <mitch@gimp.org>

	Bug 496772 – Position shown in the statusbar needs more
	precision (for some tools)

	* app/display/display-enums.[ch]: add enum GimpCursorPrecision
	which can be one of { PIXEL_CENTER, PIXEL_BORDER, SUBPIXEL }.

	* app/display/gimpdisplayshell-cursor.[ch]: add "precision"
	parameter to gimp_display_shell_update_cursor() and pass it
	on to the statusbar.

	* app/display/gimpstatusbar.[ch]: add "precision" parameters to
	the cursor coordinates APIs, offset the passed coords accordingly
	and display them with one decimal point if SUBPIXEL is requested
	and the display's unit is PIXEL. Keep a second floating-point
	format string around at any time.

	* app/tools/gimptoolcontrol.[ch]: add a "precision" member and API
	so tools can configure the precision they need. Defalt to
	PIXEL_CENTER since that's right for almost all tools.

	* app/display/gimpdisplayshell-callbacks.c: pass the tool's
	precision to gimp_display_shell_update_cursor().

	* app/tools/gimptool.[ch]: add "precision" parameter to
	gimp_tool_push_status_coords() and pass it on to the statusbar.

	* app/tools/gimpaligntool.c
	* app/tools/gimpblendtool.c
	* app/tools/gimpcolortool.c
	* app/tools/gimpcroptool.c
	* app/tools/gimpeditselectiontool.c
	* app/tools/gimpfliptool.c
	* app/tools/gimpfreeselecttool.c
	* app/tools/gimpmovetool.c
	* app/tools/gimppainttool.c
	* app/tools/gimpperspectiveclonetool.c
	* app/tools/gimprectangleselecttool.c
	* app/tools/gimprectangletool.c
	* app/tools/gimptransformtool.c
	* app/tools/gimpvectortool.c: set precision in init() where
	needed. Adjust the precision in the fly when needed, e.g. while
	moving guides or when toggling hard-edge on paint tools. Also pass
	an appropriate precision to gimp_tool_push_status_coords(), which
	is not always the tool's precision as used for cursor display.
