Adjust font size in the client itself

[Freudentaumel]

I would like to suggest that the font size can be adjusted directly in the client and not in the Windows settings. The font sizes in Windows are fine for me, but not in the client itself. The tiny default font is difficult for me to read as I wear glasses.

I played around with changing the font size in UWP apps a bit and based on my research I don't think this is something I actually could change consistently.
Yes, I was able to change the font size during runtime with a slider, but this implied more problems than it solved.
In case the user changes the system font size, I have no real way to detect this, and so some controls would adapt to the system font size and some to "my" font size.

I would have to change the font size property for each control (TextBlockStyle) in the app, which is a lot of work.
Changing it only for the chat messages themselves would be possible, thou I'm not happy with that either.

Both the font size in the settings app and the default font size in UWPX are the same.
I think this is just a foreground and background contrast problem.
