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

Some references:
  1. https://www.cairographics.org/OpenGL/
  2. https://bazaar.launchpad.net/~macslow/gl-cairo-simple/trunk/files
  3. http://ssvb.github.io/2012/05/04/xorg-drivers-and-software-rendering.html
  4. https://github.com/cubicool/cairo-gl-sdl2 - uses cairo opengl backend (but it's C++)
  5. https://cgit.freedesktop.org/cairo/ - cairo source - look in src/ for gl backend support
  6. https://cairo.cairographics.narkive.com/acXWIWzV/does-cairo-use-hardware-acceleration - old but good discussion on using GL with Cairo.
    1. 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)
