Pick materials with a switchable depth convention: the point, line and
gsplat pick wrappers (GLSL and TSL). The picking system's per-render mode
sync detects the capability via isSurfacePickAwareMaterial,
mirroring the CameraAwareMaterial guard idiom. (Mesh implements the
richer MeshPickAwareMaterial instead — ../mesh/pick-mode.ts.)
