Title's pretty self-explanatory. While lwsurfaceshader.h APIs, etc. is included in LW2018 SDK, and bears similarity to lwshader.h APIs, etc. from prior SDK, it would still be quite useful to have a proper example of using the new lwsurfaceshader.h approach to implement a simple example (and ideally, a not-so-simple example, f.e. SSS, as well).
