For Pi3 and lower using OpenVG

A few have made full dash apps using this approach.
Boots fast too.
I tried many other ways before that, with accelerated graphics in an old version of Java getting closest to the above approach.
But maintaining Linux plus Java was a pain and it booted slow
Not sure best way with Pi4/5, perhaps using Vulkan?
SD cards do boot faster now.
