This was the only function where we were deliberately creating something outside
the cache. The old cache required explicit registration with the cache. The new
cache does not. So when switching to the new cache "texture" was counted against
the budget just by virtue of being born.

+    if (texture) {
+        // TODO: It'd be nice to be able to do this before creation so we don't boot something
+        // out of the cache. We could temporarily boost the cache budget.
