Edit visuals directly in modV

[TimPietrusky]

It would be super nice to edit visual code directly in modV to also be able to use it for live coding in combination with other modules.

For shaders we could integrate https://github.com/patriciogonzalezvivo/glslEditor

Apart from the realtime controls, which modV already has through props, I'm not sure what glslEditor would bring to modV which isn't already available in a code editor or terminal.

Modules already update on filesystem changes, so editing the code live is already possible.

We actually have this as an issue #619, so we can close this.
