I almost went to implement my own undo/redo system, and then found the
egui undoer.
Went to make a small demo to test for myself how it worked, and then
found the linked issue.
So here is a tweaked version of that :)

This makes the sizing pass of an `egui_table` ensure the table uses as
little width as possible.
Subsequently, it will redistribute all non-resizable columns on the
available space, so that a table better follow the parent container as
it is resized.
I also added `table.reset()` for forgetting the current column widths.
Marking widgets as disabled was not reflected in the accesskit output,
now the disabled status should match.

The default `Plot` formatter now picks precision intelligently based on
zoom level. The width of the Y axis are is now much smaller by default,
and expands as needed.
Also deprecates `Plot::y_axis_with`; replaced with `y_axis_min_width`.
When the layers are reordered at the end of the frame, the sublayers are
placed directly above their respective parents. This allows having Areas
inside Windows, e.g., for the pan-zoom container.

All the other crates in egui have serde as an optional dependency -
which is great! But sadly egui_extras unconditionally includes it, which
adds a bunch of code to stuff that may not care for it. This PR gates
serde support behind a new `serde` feature.
This is a breaking change; if that's undesirable then we can add it as a
default feature instead, though that wouldn't match any of the other
crates.
This adds most of the "standard" easing functions from
https://easings.net/ to `emath::easing`, and adds helpers in `egui` for
using them.
In particular there is now `ctx.animate_bool_with_easing` and
`ctx.animate_bool_responsive`, that uses a cubic easing function.
All animations in egui now uses cubic ease-out, for a more responsive
feeling (fast at the start, slower towards the end).
You can now set custom tags on the `UiStack`. This allows you to write
code that is situationally aware at runtime. For instance, you could
decide wether or not a label should truncate its text depending on what
part of your ui it is in, without having to pass that info down via the
callstack.
These were confusing, because `set_enabled(true)` and
`set_visible(true)` did nothing.
Instead use one of:
* `ui.add_enabled`, `ui.add_enabled_ui` or `ui.disable()`
* `ui.add_visible`, `ui.add_visible_ui` or `ui.set_invisible()`
* Closes https://github.com/emilk/egui/issues/4327
* Closes#4534
This PR:
- Introduces `Ui::stack()`, which returns the `UiStack` structure
providing information on the current `Ui` hierarchy.
- **BREAKING**: `Ui::new()` now takes a `UiStackInfo` argument, which is
used to populate some of this `Ui`'s `UiStack`'s fields.
- **BREAKING**: `Ui::child_ui()` and `Ui::child_ui_with_id_source()` now
take an `Option<UiStackInfo>` argument, which is used to populate some
of the children `Ui`'s `UiStack`'s fields.
- New `Area::kind()` builder function, to set the `UiStackKind` value of
the `Area`'s `Ui`.
- Adds a (minimalistic) demo to egui demo (in the "Misc Demos" window).
- Adds a more thorough `test_ui_stack` test/playground demo.
TODO:
- [x] benchmarks
- [x] add example to demo
Future work:
- Add `UiStackKind` and related support for more container (e.g.
`CollapsingHeader`, etc.)
- Add a tag/property system that would allow adding arbitrary data to a
stack node. This data could then be queried by nested `Ui`s. Probably
needed for #3284.
- Add support to track columnar layouts.

### In short
You can now put interactive widgets, like buttons and hyperlinks, in an
tooltip using `on_hover_ui`. If you do, the tooltip will stay open as
long as the user hovers it.
There is a new demo for this in the egui demo app (egui.rs):
### Design
Tooltips can now contain interactive widgets, such as buttons and links.
If they do, they will stay open when the user moves their pointer over
them.
Widgets that do not contain interactive widgets disappear as soon as you
no longer hover the underlying widget, just like before. This is so that
they won't annoy the user.
To ensure not all tooltips with text in them are considered interactive,
`selectable_labels` is `false` for tooltips contents by default. If you
want selectable text in tooltips, either change the `selectable_labels`
setting, or use `Label::selectable`.
```rs
ui.label("Hover me").on_hover_ui(|ui| {
ui.style_mut().interaction.selectable_labels = true;
ui.label("This text can be selected.");
ui.add(egui::Label::new("This too.").selectable(true));
});
```
### Changes
* Layers in `Order::Tooltip` can now be interacted with
All `Area`s now have a quick fade-in animation. You can turn it off with
`Area::fade_in` or `Window::fade_in` .
The `Window` fade-out animation is now nicer: it fades all elements of
the window, not just the frame.
It can be controlled with `Window::fade_out`.
* Part of https://github.com/emilk/egui/issues/4535
* Closes https://github.com/emilk/egui/issues/3974
This adds a special `sizing_pass` mode to `Ui`, in which we have no
centered or justified layouts, and everything is hidden. This is used by
`Area` to use the first frame to measure the size of its contents so
that it can then set the perfectly correct size the subsequent frames.
For menus, where buttons are justified (span the full width), this
finally the problem of auto-sizing. Before you would have to pick a
width manually, and all buttons would expand to that width. If it was
too wide, it looked weird. If it was too narrow, text would wrap. Now
all menus are exactly the width they need to be. By default menus will
wrap at `Spacing::menu_width`.
This affects all situations when you have something that should be as
small as possible, but still span the full width/height of the parent.
For instance: the `egui::Separator` widget now checks the
`ui.is_sizing_pass` flag before deciding on a size. In the sizing pass a
horizontal separator is always 0 wide, and only in subsequent passes
will it span the full width.
* Closes#4473
This PR introduce `Style::wrap_mode`, which adds support for text
truncation in addition to text wrapping. This PR also update some width
calculation of the ComboBox.
#### Core
- Add `egui::TextWrapMode` (pure enum with `Extend`, `Wrap`, `Truncate`)
- Add `Style::wrap_mode: Option<tTextWrapMode>`
- **DEPRECATED**: `Style::wrap`, use `Style::wrap_mode` instead.
- Add `Ui::wrap_mode()` to return the wrap mode to use in the current
ui. If specified in `Style`, return it. Otherwise, return
`TextWrapMode::Wrap` for vertical layout and wrapping horizontal layout,
and `TextWrapMode::Extend` otherwise.
- **DEPRECATED**: `Ui::wrap_text()`, use `Ui::wrap_mode` instead.
#### Widget
- Update the width calculation of the `ComboBox` button (_not_ its popup
menu).
- Now, `ComboBox::width()` (defaulting to `Spacing::combo_width`) is
always considered a minimum width and will extend the `Ui`, regardless
of the selected text width and wrap mode.
- Introduce `ComboBox::wrap_mode`, which overrides `Ui::wrap_mode` for
the selected text layout.
- Note: since `ComboBox` uses `ui.horizontal` internally, the default
wrap mode is always `TextWrapMode::Extend`, regardless of the caller's
`Ui`'s layout.
- The `ComboBox` button no longer extend to `ui.available_width()` with
wrapping is enabled.
- **BREAKING**: `ComboBox::wrap()` no longer has a `bool` argument and
is now a short-hand for `ComboBox::wrap_mode(TextWrapMode::Wrap)`.
- Added `ComboBox::truncate()` as short-hand for
`ComboBox::wrap_mode(TextWrapMode::Truncate)`.
- Update `Label`
- Add `Label::wrap_mode()` to specify the text wrap mode.
- **BREAKING**: `Label::wrap()` no longer has a `bool` argument and is
now a short-hand for `Label::wrap_mode(TextWrapMode::Wrap)`.
- **BREAKING**: `Label::truncate()` no longer has a `bool` argument and
is now a short-hand for `Label::wrap_mode(TextWrapMode::Truncate)`.
- Update `Button`
- Add `Button::wrap_mode()` to specify the text wrap mode.
- **BREAKING**: `Button::wrap()` no longer has a `bool` argument and is
now a short-hand for `Button::wrap_mode(TextWrapMode::Wrap)`.
- Added `Button::truncate()` as short-hand for
`Button::wrap_mode(TextWrapMode::Truncate)`.
#### Low-level
- **BREAKING**: `WidgetText::into_galley()` now takes an
`Option<TextWrapMode>` instead of a `Option<bool>` argument.
- **BREAKING**: `WidgetText::into_galley_impl(()` now takes a
`TextWrapping` argument instead of `wrap: bool` and `availalbe_width:
f32` arguments.

This introduces the boolean field force_current_scroll_area to
InputState which will be set when scroll_with_delta is called, causing
the ScrollArea to skip the check whether it is focused and always
consume the smooth scroll delta.
* Closes#2783
* Related to #4295

I took the liberty of removing that comment since I *think* that I got
all "relevant" ones (showing up more than once, sort of).

I had to make a couple types not Copy because closures, but it should'nt
be a massive deal.
I tried my best to make the API change as non breaking as possible.
Anywhere a PathStroke is used, you can just use a normal Stroke instead.
As mentioned above, the bezier paths couldn't be copy anymore, but IMO
that's a minor caveat.

On a touch screen, if you press down on a widget and hold for 0.6
seconds (`MAX_CLICK_DURATION`), it will now trigger a secondary click,
i.e. `Response::secondary_clicked` will be `true`. This means you can
now open context menus on touch screens.
This is a refactor on the way to add support for opening context menus
on touch screens via press-and-hold.
This PR changes what `InputState::button_clicked` does (it was ver badly
named before), and also changes `Response::clicked_by` to no longer be
true if clicking with keyboard (i.e. a widget has keyboard focus and the
user presses Space or Enter).
