UI Scaling

[ghost]

I would like to see nheko support a scaling factor mechanism. This could be represented in the configuration screen via a slider with increments of 25% from perhaps 50% or 100% up to 400%. The scale factor would be used to scale the UI up (or down, for <100% factors) in order to make the application more usable for low-vision users such as myself.

Other software which provides such a feature includes:

• Telegram
• Discord
• Any web client with a responsive UI design.

Running the application with the QT_SCALE_FACTOR environment variable set to a value other than 1 does this well. Can this same behavior be set from within the app while it's running?

+1, this would be great for high DPI monitors
