Currently I'm focusing on images, but I like to add video support
later. I didn't thought of OpenGL until now. For videos I like only a
2D plane playback nothing with a 3D cube. I assume a simple draw buffer
GC or Cairo should be fast enough. But I'm not much experience with
video playback until now. I thought about using gstreamer in future
after testing a prototype on win32.
