// Setup: Put in a spare ordinary cube you own. Touch different places on one face to sample the procedural pattern at live surface coordinates. Edit the constants to design a pattern.
// Stop / restore: Disable/remove. Only private owner messages are produced; no texture or tint is applied.
// Notes: A stripe duty controls the fraction filled; it is not a smooth anti-aliased texture renderer. Surface coordinates depend on the viewer and mesh; ordinary prim faces are the clearest test surface.
