Submitted by Emmanuel Pacaud Link to original bug (#627630)
Description
Currently lasem silently fails when needed font are not installed, resulting in wrong rendering.
These fonts are ttf versions of Tex fonts: cmex10, cmmi10, cmr10.
lasemrender should emit a warning if it doesn't fint the required fonts.
lasem itself should provide a function which tests the font presence.
Version: git master
