clip2icns: Fixed a very weird crashing bug in clip2icns (the application itself wasn't crashing, but the finder was getting stuck once in a while while trying to display an icon). It was a compound problem in the compression routine, it was stopping too early (so the resource was too small) and it was interpreting and it had problems with compressing the last few pixels (it was interpreting them as a repeat area instead of copying them as is).
