Compute shader 101

This is a presentation compute shaders, the why and how. I introduce the concepts of compute shaders, tradeoffs with other ways of accessing compute power of GPUs, and then give resources and materials for getting started. The slide deck (with lots of links to other resources) is here: https://docs.google.com/presentation/d/1dVSXORW6JurLUcx5UhE1_7EZHuXv8APjx2y_Bbs_1Vg/edit?usp=sharing A couple of additional links mentioned in the Q&A: https://github.com/Co-dfns/Co-dfns http://www.jcgt.org/published/0009/03/02/ (hash functions for GPU)
