bflatastic e2637115df Displacement in the viewport's key-light shadows ...

The shadow pass draws the dense copy and displaces it like the 3D view, so a displaced surface
shadows itself instead of being shadowed as if it were still smooth.

- shaders/displace.wgsl: displace_by_height, shared by mesh.wgsl and shadow.wgsl
- the shadow pipeline takes the set bind group (height and sampler) and a displacement vec4
  (on, world units per unit of height with the height strength, vertex spacing)
- while it displaces, the cached shadow map is re-rendered when the set textures change
- test: with flat height, displaced shadows match the plain mesh's
