renderer.shading

The readings renderer.shadingOf builds out of the document the renderer publishes every frame.

• shadingSubject(value, what) answers the id a shading question names: an entity proxy's id, an entity-id string, or the registry key of a material in any form a material answers to.
• publishedRenderable(doc, id) answers the row that answers for a subject: the entity's own row, or a row drawing with the material, a fault wherever there is one.
• materialRow(doc, id) answers the renderer's record for one material.
• shadingFault(state, means, row) builds the fault reading a row carries.
