Proposal for implementing a Shadertoy node for Blender Compositor

The Need: Shadertoy is community driven and has a huge hub of coders worldwide. It's short to code WebGL and easy to understand with Shadertoy API.

Adopted Scenario: Natron has built an OFX for Shadertoy and Also a Blender build is floating around in community:

github.com/bitsawer/blender-custom-nodes

I have also built some toys for NAtron with Shadertoy only:

I can work on it too if someone can guide me on building nodes for Blender compositor. Thanks.
