Feature #792

Updated by Hammel 11 months ago

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

 Some references: 
 # https://www.cairographics.org/OpenGL/ 
 ## https://sourceforge.net/projects/gtkglext/ 
 # "Cairo git on freedesktop.org":https://cgit.freedesktop.org/cairo/?h=1.16 for the 1.16 release in Buildroot

 # http://ssvb.github.io/2012/05/04/xorg-drivers-and-software-rendering.html 
 # https://github.com/cubicool/cairo-gl-sdl2 - uses cairo opengl backend (but it's C++) 
 # https://cgit.freedesktop.org/cairo/ - cairo source - look in src/ for gl backend support 
 # https://cairo.cairographics.narkive.com/acXWIWzV/does-cairo-use-hardware-acceleration - old but good discussion on using GL with Cairo. 
 ## Buildroot needs Mesa added with vc4 support to get Cairo with GL.

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