`begin_frame`, `end_frame` is more convenient when using egui in a game engine. In particular, 0.16.0 was incompatible with https://github.com/mvlabat/bevy_egui>.
Changes:
* New `BarChart` and `BoxPlot` diagrams
* New `FloatOrd` trait for total ordering of float types
* Refactoring of existing plot items

* Rename `CursorPair` to `CursorRange`
* Easymark editor: add keyboard shortcuts to toggle bold, italics etc
* Split up TextEdit into separate files
* Add TextEdit::show that returns a rich TextEditOutput object with response, galley and cursor
* Rename text_edit::State to TextEditState
This refactors the widget state storage introduced by @optozorax in https://github.com/emilk/egui/pull/257
* Unify the four buckets (`data`, `data_temp`, `id_data` and `id_data_temp`) into a single `data`.
* Less complexity, and also less chance of error (storing in one bucket, reading from another).
* Store data by `Id` and `TypeId`.
* Users can thus reuse the same `Id` to store many types.
* Uses a simple xor of id and typeid, which is fast and good since both id and typeid are already high-entropy hashes.
* Use different suffixes on the functions to pick if you want the data persisted or not (`get_temp`, `insert_persisted`, etc).
* Writing with one suffix and reading with the other works.
* To store state not bound to a specific `Id` (i.e. only based on type), use the new `Id::null` as the key.
* Make egui_glow and opt-in backend for eframe
* Add egui_glow to Cargo.toml and to CI
* Reference egui_glow where egui_glium is mentioned
* Remove path-patches from root Cargo.toml
* Add instructions on how to enable the glow backend of eframe
* Rename epaint feature "persistence" to "serialize"
* Add separate "serialize" feature to egui
* egui_demo_lib: separate serialize and persistence features
* Add App::persist_native_window and App::persist_egui_memory
Controls what gets persisted
