Display needs to be magnifiable

[BartMassey]

Either ctl-scrollwheel or ctl-shift-+ needs to work to magnify the UI as a whole. This is pretty much a necessity both for accessibility (my vision is terrible) and for hi-DPI screens (I'm using a 4K monitor). If I understand correctly, the decision to work in screen coordinates may make this hard: however, it's a must-have for any application that is intended for widespread web deployment.

This is a great point, and actually should not be too hard to implement. I already have a slider for scaling up the UI, so hooking it up to the appropriate events shouldn't be too much work.

Sweet!

any chance to get dpi configurable also for desktop backends? (for example via optional env var)

[emilk]

@actionless It is already configurable with https://docs.rs/egui/latest/egui/struct.Context.html#method.set_pixels_per_point

[actionless]

@emilk my point was what in case of browser backend user can change the scale themselves by using Ctrl+Scroll or such

while on desktop scale could be changed only if the developer will add some custom code for that, so having env var to configure it (like in GTK or Qt) would be useful
