What went wrong

The transform gizmo scales inversely with the size of the viewport

as it turns out this isn't related to the viewport size, but rather the distance to the camera.

It also appears to be affected by the angle

if no one is working on this, I'd be happy to give it a shot!

I think it's a perspective issue. Transform gizmos in Godot work the same way—if they're close to the camera, they look small, but when they're far away, they appear huge, even though they are actually the same size.

In the image, the first and second rows show screenshots from two perspectives in Godot (left) and Bevy (right). The third row shows these images overlaid.

Perhaps we should fix the issue with resizing, and tune down the rate at which it increases in size since it does feel a bit ridiculous to be that big that quickly

In that draft, I've fixed the resizing issue. If you have time, could you check it out?
