Feature suggestion: A master camera object which defines the canvas

[ghost]

Hello. I have a suggestion

When you create a new project, it asks for dimensions of the document. Instead of using a static document size, I think it would be better to have a master "camera" object, where you instead define the camera's aspect ratio, and by default it points at x:0 y:0, with a default zoom level of 100%.

This way, you can keyframe the camera to zoom, pan, or rotate the view of the underlying artboard. Vector graphics have no arbitrary boundaries (e.g. you can draw a rectangle at -10000,-10000 if you want to) and they are infinitely scalable, so simulating a camera in this type of software would work very well.

When exporting, everything outside of the camera perspective would simply be clipped from view in a master clipping box.

Maybe it could be used as inspiration for enve
