AssetTextureStreamSource

Remarks

The join AssetTextureSource is the one-shot half of. That one reads a whole Texture artefact and decodes it; this one reads a range of the same artefact and decodes nothing, because a page is bytes the device wants as they are.

⚠ A stream per read, not a stream per texture. Pages of one texture are read concurrently on the thread pool, and a shared stream has a position two of them would fight over — the resulting bug is a page holding another page's bytes, which looks like a corrupt texture rather than like a race. Opening is a catalog lookup and a slice of an already-mapped bundle, so the cost of doing it per page is not the cost it looks like.
