[Feature request] Digital zoom hotkeys for camera mode

[parkerlreed]

Is your feature request related to a problem? Please describe.

I am using my phone as a desktop magnifier. My current solution for zooming involves zooming into the desktop itself, which is less than ideal for a high resolution sensor rendering on something like 1080p.

Describe the solution you'd like

Digital zoom shortcuts taking advantage of high resolution sensor sizes (4032x3024 in my case)

Describe alternatives you've considered

Zooming into desktop which nets you a maximum of the rendered desktop resolution.

Additional Info

Max sensor size fullscreened to desktop

Zooming in with desktop zooming

Resizing the window to much larger than the desktop

Desktop zooming into that with much more detail

I have this feature in mind for the future (and other camera-related features like turn on/off flashlight). It requires to adapt the control mechanism first, because currently camera implies no control. #4452
