Infrastructure for using ShaderToy as a test corpus about rust-gpu HOT 5 OPEN

I hand ported three shaders from shadertoy...I think automating this is doable for most of the image shaders. It would be cool to have a harness that compares rendering results.

Example, which works with mouse too:

Ported from https://www.shadertoy.com/view/DlGfzh. Code in https://github.com/LegNeato/rust-gpu/tree/fork-shield

Update: I have a WIP PR to make naga translate to rust.

Update: I have a WIP differential harness that compares the original shadertoy shader and the converted rust shader's output.
