Distance fields are ok for VR/AR applications, but not accurate 
enough and wastes way too much resources for a generic UI that 
covers all platforms and use-cases.

This is where the game-engine mindset goes wrong: A generic 
portable UI framework should leave as much resources as possible 
for the application (CPU/GPU/Memory/power). You don't need to do 
real time scaling at a high frame-rate in a generic UI.

So, even if you can get to a game-engine-like solution that only 
use 5% of the resources on a high end computer, that still 
translates to eating up 50% of the resources on the low-end. 
Which is unacceptable. A UI framework has to work equally well 
with devices that is nowhere near being able to run games...
