* Let 1D strips fill up parent width/height
* Add Strip + Table + DatePicker to egui_extras changelog
* Expose some dragging- and pointer related context/memory methods
* Make tables resizable
This can be used, for instance, to:
* Render things to offscreen buffers.
* Read the pixel buffer from the previous frame (glow::Context::read_pixels).
* Render things behind the egui windows.
* Rename AlphaImage to FontImage to discourage any other use for it
* Encode FontImage as f32 and postpone the alpha correction
* Interpret alpha coverage in a new, making dark text darker, improving contrast in bright mode
The epaint tessellator uses "feathering" to accomplish anti-aliasing. This PS allows you to control the feathering size, i.e. how blurry the edges of epaint shapes are.
This changes the interface of Tessellator slightly, and renames some options in TessellationOptions.
* Fix code that could lead to a possible deadlock.
Drop implementations are not called until the end of a statement. The statement changed in this commit therefore took 4 read locks on a RwLock which can lead to problems if a write lock is requested between any of these read locks. The code looks like it would only hold one lock at a time but it does not drop any of the locks until after the arithmatic operations complete, which leads to this situation. See https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=996079046184329f3a9df1cd19c87da8 to see this in action. The fix is to just take one lock and share it between the three calls to num_presses, letting it drop at the end of the scope.
* Fix code that may cause a deadlock in `MenuRoot::stationary_interaction`
The issue here is related to that in 9673b8f2a08302c10ffcfd063f2dbdec4301d3e2 in that the lock is not dropped when it is expected. Since the `RwLockReadGuard` produced by `ctx.input()` has a reference taken from it (one into `pointer`), the lock cannot be dropped until that reference is no longre valid, which is the end of the scope (in this case this function). The following `ctx.input()` then attempts to aquire a second lock on the `RwLock`, creating the same situation that was found in the referenced commit.
This has been resolved by holding one lock on the input for the whole function.

This adds a callback (set by `Context::set_request_repaint_callback`)
which integration can use to wake up the UI thread.
eframe (egui_web and egui_glow) will use this, replacing
`epi::Frame::request_repaint`.
Existing code calling `epi::Frame::request_repaint` should be changed
to instead call `egui::Context::request_repaint`.
This is the first callback added to the egui API, which otherwise is
completely driven by data.
The purpose of this is to remove the confusion between the two
`request_repaint` methods (by removing one). Furthermore, it makes
`epi::Frame` a lot simpler, allowing future simplifications to it
(perhaps no longer having it be `Send+Sync+Clone`).

This is a good early-out for widgets in `ScrollAreas`, but
also prepares for speeding up the first pass of a possible two-pass
version of egui: https://github.com/emilk/egui/issues/843
* 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.
