ObjectIdShader class final

object_id.frag: the id the renderer handed this draw, as three bytes.

One attachment: the picking target has no surface buffer beside it, so nothing is written to the context's second output, the way the shadow stages leave it.

A masked material's hole is a hole here too: the alpha is the one readSurface computes — texel, tint, vertex colour — held against the cutoff in IdInfo.mask.x, and a fragment under it is discarded before the id is written, so a click through the hole answers with what is behind it.
