Changes  view on Meta::CPAN

 - release image row and comments memory on all error returns in gif
   reader

 - handle zero length extensions, previously this would cause a null
   pointer dereference
   Thanks to Krzysztof WojtaÅ› for the test data and fix for this.

 - an integer division meant that preview scaling to below 1 pixel
   wide or high (which isn't too useful anyway) was calculating using

   Thanks to David Cantrell for producing a backtrace of the crash on
   his Alpha-NetBSD CPAN test box which made it possible to track this
   down.
