Having never used retained mode Im struggling to understand how 
it's going to result in a vast saving in terms of code you have 
to write. I mean somewhere someone has to write the code that 
draws the widget, i dont see how immediate mode makes that any 
different.

Also I kind of hate the fact that alot of modern apps have such 
laggy GUIs, I mean it's seriously fucking pathetic that with all 
the silicon we have simple apps like spotify are laggy when 
drawing. Even VS Code feels laggy to me.

My vote would be choice, if you force one mode or the other then 
you will lose people, and you need people, developers and users.

Will all the rendering be on the GPU? My experience is that in a 
lot of cases 2D rendering is done on the CPU. Font rendering is 
generally still done on the CPU afaik.

Ok, so it's retained mode and GPU rendering. A bunch of people 
just left the room.

And you seriously think it's 10 lines vs 1000 lines? I'm asking 
not criticising since I dont really know how retained mode works 
tbh.
