2003-05-05 Michael Natterer <mitch@gimp.org> * app/display/gimpdisplayshell-scale.[ch] (gimp_display_shell_scale_zoom_fraction): new utility function which takes GimpZoomType and zooms "scalesrc" and "scaledest". (gimp_display_shell_scale_calc_fraction): new utility function which takes an exact double scale factor and calculates "scalesrc" and "scaledest". (gimp_display_shell_scale): use the first. (gimp_display_shell_scale_fit): use the second. * app/tools/gimpmagnifytool.[ch]: use the first to click-zoom and the second to area-zoom. Fixes bug #112115. Removed zoom_in() and zoom_out() utiliy functions. Removed "GimpZoomType op" from the GimpMagnifyTool struct. Cleanup.
