Unleash the Gizmo Size!

please consider unleashing the Gizmo size. Right now it goes to 200 px, which is waaaaaayyyyy too confined for 2023. We should be able to increase it to at least 400 px, but why stop there?

Reasoning. While gizmo size matters very little for scale and translation... it does a whole world of difference for trackball rotation. The bigger the gizmo the more inherent precision you get - disregarding the otherwise quite handy shift key there.
