| | | | | | | | | | | | About 9x faster than Murmur3 for long inputs. Most of this is a mechanical change from SkChecksum::Murmur3(...) to SkOpts::hash(...).

* Switch uses of SkChecksum::Compute to Murmur3.Gravatar mtklein2015-11-16
| | | | | | | | | | | | | | | SkChecksum::Compute is a very, very poorly distributed hash function. This replaces all remaining uses with Murmur3. The only interesting stuff is in src/gpu.

* Some usability ideas around SkTHash.Gravatar mtklein2015-03-20
| | | | | | | | | | | | | | - By default, use new SkGoodHash to hash keys, which is: * for 4 byte values, use SkChecksum::Mix, * for SkStrings, use SkChecksum::Murmur3 on the data, * for other structs, shallow hash the struct with Murmur3. - Expand SkChecksum::Murmur3 to support non-4-byte-aligned data. - Add const foreach() methods. - Have foreach() take a functor, which allows lambdas.
