For 45 degrees rotating I can see this, but I'm rotating a 16x16 surface 90 degrees. Still, I could understand if the algorithm needs to increase the resulting surface.

And maybe pygame.transform.rotozoom then does it correctly, but pygame.transform.rotate doesn't.

Information is lost on the edges and undocumented information is added. Does it use a default/background/palet color for setting the "required" extra pixels?  If so, pygame.transform.rotozoom and pygame.transform.rotate in my testing seem to use different colors for that same task.

Still thinking something is wrong. Maybe because I see it in my test case...
