otini discovers math typesetting
These fraction rules are too thick; but which value am I to use? The math constants table of my math font (XITS) says 0.66, but 0.66 what? 😕
This is a challenge for typographers (which I am not). Can you tell apart our rendering (amateurish) from LuaLaTeX's?
@otini I'd say yours is the one on the left because the spacing between the subscripts and the variables in the second line seems off.
