-/**
- * Shader that down-sample depth buffer, creating a Hierarchical-Z buffer.
- * Saves max value of each 2x2 texel in the mipmap above the one we are rendering to.
- * Adapted from http://rastergrid.com/blog/2010/10/hierarchical-z-map-based-occlusion-culling/
- *
- * Major simplification has been made since we pad the buffer to always be bigger than input to
- * avoid mipmapping misalignement.
