Try adding opengl to cairo in Launcher

01 - Critical
This is an experiment to see if we can speed up the UI.Some references:
- 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)
