// the probe of the occupied cab in the vulkan renderer (the stage A4 of the plan, opengl46_cab_probe): the maps of gfx::cab_probe,
// which tells when they're drawn and what the shading reads. the six faces are drawn at once by multiview (cabprobe.vert reads the
// face from gl_ViewIndex) instead of the geometry shader of the opengl renderer; the renderer draws to the target the class keeps
// (target()), makes the mipmaps and the spherical harmonics (vulkan14cabprobe.cpp)
