2004-04-05 Pedro Gimeno <pggimeno@wanadoo.es> Sanitize rectangle and ellipse selection handling (bug #138237 and bug #138103): * app/tools/gimprectselecttool.h * app/tools/gimprectselecttool.c (GimpRectSelectTool): new member "moved" indicating whether the cursor was moved after the click. (gimp_rect_select_tool_coords_to_integer): New function for consistent conversion of the rectangle FP coords to pixels. (gimp_rect_select_tool_button_press, gimp_rect_select_tool_button_release, gimp_rect_select_tool_motion, gimp_rect_select_tool_draw): use it instead of fiddling with the FP coordinates. Update "moved" and use it to detect whether the selection needs to be cleared. * app/tools/gimpellipseselecttool.c (gimp_ellipse_select_tool_draw): use the new coords_to_integer function.
