I haven’t work on rendering for a while, and I always on the Qt ship. I am keep getting question about build embedded application for startup.

let’s get to the basic of the GUI rendering.

1. layout engine where should I put that box? not only that one box, but also all the children box and its sibilings. box size, or calculated from flex open source: yoga

so the GUI can render the logic layout to the actual layout

1. rendering engine GPU: skia. but it have the common issue with GPU. CPU: blend2D

the dependecies: webp, jpeg freetype, shader..etc

1. DSL QML, HTML/CSS how to describe the layout and behavior

2. scripe engine why? because seperatation of static and dynamic part. Qt v4 javascript engine. QuickJS, and Lua from 云风

3. message engine signal/slot and cross-thread
