I made many transitions in Gimp from scratch. I still have some tweaking to do, but I plan to have these 320x240 transitions setup as animations. Of course, I plan to have these as CC0, so they will be free for any usage.
What does everyone think? Did I miss any basic transition?

Remark: When the feature drawable:set_pixels is done, we could make some of these directly with code (without need of png images) and with a much smoother animation.
