I have seen many people using this techniques which is Signed Distance Field Font Rendering. And I see it's kinda easy to implement. Someone demonstrated this using Cinder, but should be doable in orx too. The link is here https://forum.libcinder.org/topic/signed-distance-field-font-rendering
Though, we see less and less text in games nowadays but they are not totally gone. This is not a feature request post, just letting people know that this is another way of rendering cool fonts
I stumbled upon Valve's paper about 4 years ago, when I was making my dfrm test, and did a quick test with orx which worked great.
I quickly tried to add the feature to the engine but did not find a elegant way to handle the shader part behind the scene.
Maybe I'll give it another thought soon.
