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. svn path=/trunk/; revision=26681
