Shader graph

[adriengivry]

Implementing an editor tool that can generate a glsl file using a node based approach.

We should be able to create:

• Input nodes
• Maths functions
• Buffer inputs
• Output nodes
• Conversion nodes
• Variable declarations

We should be able to create the graph using OvUI

I am currently working on a Node based shader graph system but my approach is to use a already working graph system made by thedmd.
In my opinion it is easier to go this way instead of trying to use the existing OvUI, correct me if I am wrong.

Yep this issue suggests exactly that, we should use this kind of tool, and wrap it inside of OvUI like the rest of ImGUI.
