feat: Add zoom in button on hold alt.

[shanecelis]

Zoom out is so useful it deserves its reciprocal zoom in. Currently activated by holding the alt key.

Super idea!
Just tested, it works so well.
(On macOS, the button to maintain to ZoomIn is "Option".)

Nice!

Since you’re in here, do you see how would could add to the KDL a show/hide option for a given viewport? Actually we do that for the grid already, I suppose that pattern would work. I need to turn off the cube for the RC Jet chase cam, and a few other constrained views. I wonder if there is a window size that we should auto hide it when it’s too big for the space practically

We already have show_view_cube (default true) on viewport-kdl. Should we improve it?
