* Speed up galley cache by only using the hash as key This hashes the job but doesn't compare them with Eq, which speeds up demo_with_tessellate__realistic by 5-6%, winning back all the performance lost in https://github.com/emilk/egui/pull/682 * Remove custom Eq/PartialEq code for LayoutJob and friends * Silence clippy * Unrelated clippy fixes
