UgcRays::Scene answers the two ray queries the UGC server makes: the nearest
hit for the hidden faces' paths (never the triangle a path leaves) and any hit
for the ambient occlusion rays. Two backends:
- builtin: the two hierarchies the queries had before, moved unchanged (each
built the first time it is asked), so the files made are the same bytes
- embree: Embree 4 on the job's thread (a device per worker thread, no threads
of its own, so its time counts in the CPU budget), watertight, the skipped
triangle filtered out
UgcHsr::Options::rays and UgcRender::AoOptions::rays pick the backend; both
default to builtin, and nothing sets them yet.
Check: the UGC tests (builtin's files keep their hashes; UgcRays tests compare
embree's hits, hidden faces and occlusion with builtin's).

- The client puts a shape in its sorted, blended pass only when its
NiMaterialProperty alpha is under 0.99999 (ShaderCommon::GetAlphaFlags
0x0109f5a0; the NiAlphaProperty blend flag isn't read); at 1.0 it's drawn
solid with blending off. Transparent (and transparent glitter) shapes now
get a material with alpha 0.9999, as the S01_Alpha shapes of the game's own
brick models (res/BrickModels/ndmade) do; opaque shapes keep 1.0. Models
with a transparent brick change; the others are byte for byte the same.
- dUgcServer's files move into Bricks/, Model/, Render/, Formats/ and
Processing/ (the CMakeLists says what each holds); includes are unchanged.
