alt.use
alt.use Always use alt to display equations

## Description

When an (informal) equation contains both alt and another element (graphic, etc.), and when tex.math.in.alt is not set to 'latex', the alt element is not used to display the equation since it is considered as a fallback element. Set alt.use to force the use of alt as default rendering element even when tex.math.in.alt is not set to 'latex'.
