There's an unconditional clone when we merge trackers, even if the tracker already owns that resource. This clone has been staring me in the face. This was a quick experiment to see if it would help. According to our benchmarks, it doesn't. HOWEVER, the benchmarks never re-use textures between bind groups. There's a 1:1 relationship between a set of textures and a bind group. We also only ever bind a bind group once. This just... isn't terribly realistic. We need to modify our render benchmark to be more representative. That's more than the 10 minutes I had timeboxed for this experiment tho.
Also this PR is wrong wrt Weak handling.
Edit: ayy funny number
