eXtensible Shading Language (.xsh)
eXtensible Shading Language (.xsh) é um proto-formato de documento XML atualmente em desenvolvimento, projetado para representar infraestruturas de compilação de shaders, pipelines, draw techniques e acessórios de material. Não possui um formato definido porque atualmente serve apenas para o Qwadro ler descritores envolvimento um código GLSL. Futuramente, explanarei mais sobre a proposta.
