 // This function takes the output of a SaveAs dialog: a filename, a filter and

 // returns back the filename with the appropriate extension tacked on. If the
 // user requests an unknown extension and is not using the 'All files' filter,
 // the suggested extension will be appended, otherwise we will leave the
 // filename unmodified. |filename| should contain the filename selected in the
 // SaveAs dialog box and may include the path, |filter_selected| should be
 // '*.something', for example '*.*' or it can be blank (which is treated as
 // *.*). |suggested_ext| should contain the extension without the dot (.) in
