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.
