"Zoom to fit" option for the Corona VFB (just like the one that VRay already has)

What I´d love to see is an option that VRay already has which is called "Zoom to fit" in the Framebuffer. Whenever I render an image with Corona in a certain resolution it´s either too small in the framebuffer or it´s already zoomed in so that I cannot see the full image that I´m currently rendering.

As I mentioned, VRay already has this option and as someone who also uses VRay a lot it´d be great if we could have this in Corona, too.

The option for VRay is called "Zoom to fit" and the description says "Zooms the current image to fit in the VFB. If Render Region is active – zooms to the region."

Imo this would be an increcible "quality of life" feature!
