CTA5. From what I can find, there are only two aspect ratios: 4:3 and16:9. I'd like to use 9:16. For now, I've created a white 16:9 PNG to denotethe safe zone, but it seems there must be a better way. Is there a way tochange the aspect ratio? Can the safe area of the stage be adjusted to reflectthis, or could a template be created?
