I wanted to write everything from scratch and use as little third 
party code as possible. so I wrote my own UI system which i 
simply call "widget". and writing the software renderer for it 
was really fun and a huge learning experience. aside from 
rasterizing and only updating the pixels which actually changed, 
multit hreading the drawing loop gave the biggest performance 
boost and D made that super simple to implement
