   Sprite Editor
  I was looking for a good sprite editor to use in creating animations.  The only one I found was Tile Studio.  It's great for editing maps but its not as robust for creating sprite anims (esp if the frames are of varying sizes).  If someone could recommend a reputable (free) sprite editor for this purpose that would be great!  However, I have a feeling I might end up having to tackle this on my own.  So I was wondering if you guys could suggest what window/gui frameworks/libraries might be the most useful in this scenario to get an editor up and running as quickly and painlessly as possible on a win32 platform.  Thanks!
