Getting started

Basic ideas: this is part of graphics rendering pipeline.  The
computation is a side effect of consuming and generating a texture.

There are two pipelines to use:
- vertex shader
- fragment shader / pixel shader

We use the pixel shader, and align the texture pixels with the output array.
