Hypertext font size doesn't scale with window size

[Zughy]

Minetest version

5.7.0, 5.6.0 and so on

OS / Hardware

Happens on different hardware and different OS

Summary

Title. Every text in the following screens is a hypertext

about 1920x1080

about 1280

about 1000

about 600

Steps to reproduce

Join A.E.S. server and open your Block League profile (the one in the screen) by doing /bleague profile

Remotely related: if you use a wider text font, like OpenDyslexic, it's going to eventually push some boundaries in this pixel-fixed layout.

How does this relate to #13858?

@sfan5 tested on latest dev, both with and without fixed size in size[] fs element. Still the same

• Scaling font size with window size wouldn't make sense. This isn't done anywhere else in Minetest and I haven't seen it being done in other software either.

  Why would the user want a smaller, less readable font size just because they're using a smaller window? How would you determine the "standard window size" that corresponds to the "standard font size" for scaling?

• The real problem in your example is that formspec coordinates (GUI elements) scale with window size. This doesn't make much sense, Minetest is the only software I know doing this. This is something the formspec replacement will hopefully do better.

  This behavior can be disabled via fixed-size formspecs, i.e. size[x,y,true]. This should fix the problem in your example. I just joined A.E.S. and did /bleague profile. The problem is actually already fixed there, the formspec has already been changed to be fixed-size.

• Improve formspec scaling #14840 would have fixed your example too, without needing to make the formspec fixed-size. It basically stops formspecs from scaling down with window size too far until it's actually necessary.

Thank you @grorp for looking into this, closing then :)
