Feature #792

Updated by Hammel about 1 year ago

This is an experiment to see if we can speed up the UI. 

 Some references: 
 # - uses cairo opengl backend (but it's C++) 
 # - cairo source - look in src/ for gl backend support 
 # - old but good discussion on using GL with Cairo. 
 ## Buildroot needs Mesa added with vc4 support to get Cairo with GL. 
 # "Update to VC library to allow X11 EGL on RPi": 

 Might want to bump to latest release (1.17.2) from Buildroot's 2020.02.4 LTS current (1.16.0)
