- vr.log_performance reports how long the first-person pose takes a frame
(its animation and the arms), how often it is built, and the arms' part
of it (halo_vr_timing_start/_end).
- Once per hands model it logs how many triangles hang from each node and
how many of those from the skeleton's root ('frame bone24'), read from
the part's own buffers (rasterizer_model_buffer_data, after
HaloCE-Quest-VR, CC0). In the emulator the cyborg's hands have none on
the root: the ribbons of e377e4dc did not come from root skin.
