Relying on TypeId being some hash internally isn't future-proof because there is no guarantee about internal layout or structure of TypeId. I benchmarked TypeId noop hasher vs fxhash and found that there is very little difference.
Also fxhash is likely to be better supported because it is widely used in rustc itself.

* move print diagnostics to log
* entity count diagnostic
* asset count diagnostic
* remove useless `pub`s
* use `BTreeMap` instead of `HashMap`
* get entity count from world
* keep ordered list of diagnostics
* only update global transforms when they (or their ancestors) have changed
* only update render resource nodes when they have changed (quality check plz)
* only update entity mesh specialization when mesh (or mesh component) has changed
* only update sprite size when changed
* remove stale bind groups
* fix setting size of loading sprites
* store unmatched render resource binding results
* reduce state changes
* cargo fmt + clippy
* remove cached "NoMatch" results when new bindings are added to RenderResourceBindings
* inline current_entity in world_builder
* try creating bind groups even when they havent changed
* render_resources_node: update all entities when resized
* fmt
