* Clip by default
* Fix some spacing bugs
* datepicker: look nicer in light mode
* datepicker: show month names
* Table: don't allow resize of last column if it is Size::Remainder
* 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.
The purpose of this is to expose `frame.storage()` and `frame.storage_mut()` so users can save/load app state from the `App::update` function, without having to add another parameter to that function.
Changes:
* Added `Frame::storage()` and `Frame::storage_mut()`
* `App::update` now takes a `&mut Frame` rather than just `&Frame`
* `Frame` is no longer `Clone` or `Sync` (doesn't have to be since https://github.com/emilk/egui/pull/1366)
* 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
It was noted that the problems with Firefox on Linux/MacOS have been resolved in #1377 and the limitation on the canvas size was lifted in commit 465c96122c
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.
* Expose more tessellator method
* Make public the Tessellator methods to tessellate a circle, a
mesh, a rectangle, a line, a path, a quadratic and cubic
bezier curve.
* Add doc to tessellate_text.
* Add Mesh::append_ref method.
* Make tessellate_text take a reference
* Fix breaking change in benchmark
* 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 9673b8f2a0 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`).
* Add Shape::Callback to do custom rendering inside of an egui UI
* Use Rc<glow::Context> everywhere
* Remove trait WebPainter
* Add glow::Context to epi::App::setup
