OptionalblendInitial Material.blendMode; defaults to "normal".
OptionalcolorInitial color, copied into the material's own array. Defaults to opaque
white [1, 1, 1, 1], so an untinted material shows the lighting alone.
OptionalcolorInitial Material.colorWrite; defaults to true.
OptionaldepthInitial Material.depthTest; defaults to true.
OptionaldepthInitial Material.depthWrite; defaults to true.
OptionalmapInitial LitMaterial.map — the albedo texture sampled with the
geometry's uvs (§53, §77). Defaults to null.
OptionalopacityInitial Material.opacity; defaults to 1 (fully opaque).
OptionalstencilInitial Material.stencil; defaults to undefined (no stencil
test). A StencilState, which validates itself at construction.
OptionaltransparentInitial Material.transparent; defaults to false.
Construction arguments of LitMaterial — its own colour, plus §57's shared render state from MaterialOptions.
