As can be seen on the
wiki page about fonts, they usually have 2-3 parts separated by a pipe. First is the font file or an alias, then the font size and optionally a modifier for the style. Today I was asked if I can change some text to have an outline instead of a shadow and after some looking around I found "thick-outline" which does what it says, but looks a bit stupid as it changes the spacing between characters. They are not documented anywhere and besides "soft-shadow-thin", "soft-shadow-thick" and "thick-outline" no other type is used in the UI source, so I was wondering if there are any others that are just unused?
