* Added plot items:
* Arrows, also called "Quiver plots" in matplotlib etc.
* Convex polygons
* Text
* Images
Other changes:
* Make HLine/VLine into PlotItems as well.
* Add a "fill" property to Line so that we can fill/shade the area between a line and a horizontal reference line.
* Add stems to Points, which are lines between the points and a horizontal reference line.
* Allow using .. when specifying ranges for values generated by explicit callback functions, as an alias for f64::NEG_INFINITY..f64::INFINITY
* Allow using ranges with exclusive end bounds for values generated by parametric callback functions to generate values where the first and last value are not the same.
* update changelog
* add legend background
* Use old 1.51 toolchain instead of bleeding edge
1.52 and 1.53 has problems with incremental compilation,
so some people chose to stay on 1.51 for now.
So let's make sure egui supports 1.51 for a while!

* add a toggle for the legend
* changes based on review
* improve legend behavior when curves share names
* translate touch events from glium to egui
Unfortunately, winit does not seem to create _Touch_ events for the touch pad
on my mac. Only _TouchpadPressure_ events are sent.
Found some issues (like
[this](https://github.com/rust-windowing/winit/issues/54)), but I am not sure
what they exactly mean: Sometimes, touch events are mixed with
touch-to-pointer translation in the discussions.
* translate touch events from web_sys to egui
The are a few open topics:
- egui_web currently translates touch events into pointer events.
I guess this should change, such that egui itself performs this kind of
conversion.
- `pub fn egui_web::pos_from_touch_event` is a public function, but I
would like to change the return type to an `Option`. Shouldn't this
function be private, anyway?
* introduce `TouchState` and `Gesture`
InputState.touch was introduced with type `TouchState`, just as
InputState.pointer is of type `Pointer`.
The TouchState internally relies on a collection of `Gesture`s. This commit
provides the first rudimentary implementation of a Gesture, but has no
functionality, yet.
* add method InputState::zoom()
So far, the method always returns `None`, but it should work as soon as the
`Zoom` gesture is implemented.
* manage one `TouchState` per individual device
Although quite unlikely, it is still possible to connect more than one touch
device. (I have three touch pads connected to my MacBook in total, but
unfortunately `winit` sends touch events for none of them.)
We do not want to mix-up the touches from different devices.
* implement control loop for gesture detection
The basic idea is that each gesture can focus on detection logic and does not
have to care (too much) about managing touch state in general.
* streamline `Gesture` trait, simplifying impl's
* implement first version of Zoom gesture
* fix failing doctest
a simple `TODO` should be enough
* get rid of `Gesture`s
* Provide a Zoom/Rotate window in the demo app
For now, it works for two fingers only. The third finger interrupts the
gesture.
Bugs:
- Pinching in the demo window also moves the window -> Pointer events must be
ignored when touch is active
- Pinching also works when doing it outside the demo window -> it would be nice
to return the touch info in the `Response` of the painter allocation
* fix comments and non-idiomatic code
* update touch state *each frame*
* change egui_demo to use *relative* touch data
* support more than two fingers
This commit includes an improved Demo Window for egui_demo, and a complete
re-write of the gesture detection. The PR should be ready for review, soon.
* cleanup code and comments for review
* minor code simplifications
* oops – forgot the changelog
* resolve comment fee8ed83db (r623226656)

This adds a new `zoom_delta` to input.
This is hooked up to ctrl-scroll on egui_web and egui_glium.
Browsers convert trackpad pinch gestures to ctrl-scroll,
so this means you can not pinch-to-zoom plots (on trackpad).
In the future we can support multitouch pinch-to-zoom via the same
`InputState::zoom_factor()` function

* Fix carg doc web (add wasm32 target)
* Fix intentionally broken doc-link
This enables functions that return `impl Widget`, so that you can
create a widget by just returning a lambda from a function.
For instance: `ui.add(toggle(bool))` (instead of `toggle(ui, bool)`)
Add support for primary, secondary and middle mouse buttons. Also improve ability to click things in low FPS situations.
This introduces a lot of breaking changes:
Backends/integrations now pass mouse events via the even stream.
Response has an interface of mostly methods instead of public members.
input.mouse is now input.pointer and has new interface.
* Rename 'mouse' to 'pointer' everywhere (pointer = mouse or touch)
* Make Response::clicked and Response::double_clicked into methods
* Remove Response::active and add dragged() and interact_pointer_pos()
* Support multiple mouse buttons
* Make PointerState interface all methods
* Make most members of Response private
* Wrap Layout and Region into a new struct Placer
* [egui] Add a simple grid layout
* Refactor CollapsingHeader code (simplify header painting)
* Fix: allow putting a CollapsingHeader inside of a grid layout
* [demo] Add a widget gallery
Closes https://github.com/emilk/egui/issues/88
* Add optional striped grid background
