### Added

- Add function to set metrics and size simultaneously
- Cache `rustybuzz` shape plans

- Allow Clone of layout structs
- Move cursor motions to new `Motion` enum, move handling to `Buffer`
- Ensure that all shaping and layout uses scratch buffer
- `BufferLine`: user `layout_in_buffer` to implement layout

- Add size limit to `font_matches_cache` and clear it when it is reached
- Update `swash` to `0.1.12`
