* Remove code which uses the font size setting to position text and images. Instead use Minetest's hypertext formspec element
* Rewrite many parts of the guide contents, e.g. "you" -> "we", more detailed portal description
* Add a setting to permit viewing it in the overworld (enabled by default)
* Update the Readme
I have set the font size to 24, which works well for me on a 1920x1080 screen with somewhat high DPI. The text written in hypertext apparently ignores the Minetest font size setting, so it may look bad on different screens.
