Detailed Description

Widget for viewing the frames in the animation using SDL. This widget also serves as videoview widget for displaying video from an external source by grabbing through the harddrive.

Note: I'm considering redesigning the entire framework around this class, both to make it more intuiative and to work with dynamic plugins for filters such as onionskinning, diffing, you name it! (plugins are cool) =) However this is not very important and is left for a weekend where i'm bored :p
