* Speed up mvt_value comparison
* Converting repetitive ifs to cases
* More conversions from ifs to cases
* Optimize the always-true filter case
* Don't convert types of attributes without accumulators
* Unordered map seems to be faster than map
* Add missing header
* Fix some warnings
* Fix the warnings better
* Avoid an int->string->int conversion
* Lazily initialize layer key and values maps when actually needed
* More switches from maps to unordered_maps
* Sure, I'll take the microoptimization
* More emplacement
* Save some copies
* Emplaces and moves
* Lazy linear scan of attributes instead of building a map
* Extra printfs, missing header
* Avoid clipping if the input and output tiles are the same
* But do clip if the tile extent is being reduced
* Make sure I'm not constructing std::strings here at runtime
* More worrying about runtime string construction
* A couple more std::moves
* Const references!
* More const references
* Another std::move
* Make the string_value of mvt_value std::optional
* Reserve storage when decoding
* Provision for different mvt_values to share a string pool
* Use the string pool when decoding
* Avoid another string construction
* Try limiting the depth of the search for duplicate attributes
* Revert "Try limiting the depth of the search for duplicate attributes"
This reverts commit 9ec94a15ff.
* Update changelog
* Fix typo noticed during code review
