vwebp: fix window title when options are given

Browse Source 
Options can precede the file name. This still won't be correct for
Unicode file names, but an approximation will be displayed (with '?'s)
rather than the first character if kParams.file_name were used.
glutCreateWindow() looks like it will prohibit correcting this as it
expects an ASCII string.
