//! Touch service, properties, events and other types.
//!
//! The example below defines a window that shows the active touches and prints the touch state changes. The
//! touch's text follows the first touch position.
//!
//! ```
//! use zng::prelude::*;
//! # let _scope = APP.defaults();
//!
//! # let _ =
//! Window! {
//!     child_align = layout::Align::TOP_LEFT;
//!     child = Text! {
//!         txt = touch::TOUCH.positions().map(|p| {
//!             let mut t = Txt::from("[\n");
//!             for p in p {
//!                 use std::fmt::Write as _;
//!                 writeln!(&mut t, "   ({:?}, {:?})", p.touch, p.position).unwrap();
//!             }
//!             t.push(']');
//!             t.end_mut();
//!             t
//!         });
//!         font_size = 1.4.em();
//!         layout::offset = touch::TOUCH.positions().map(|p| match p.first() {
//!             Some(p) => layout::Vector::from(p.position.to_vector()) - layout::Vector::new(0, 100.pct()),
//!             None => layout::Vector::zero(),
//!         });
//!     };
//!     touch::on_touch_input = hn!(|args: &touch::TouchInputArgs| {
//!         println!("touch {:?} {:?}", args.touch, args.phase);
//!     });
//! }
//! # ;
//! ```
//!
//! Touch events are send to the top widget under the touch point. This module also provides touch exclusive gestures like
//! tap, touch enter/leave and [`on_touch_transform`]. Note some touch gestures are composed with others in [`gesture`] to provide the
//! final pointer gestures. You should prefer using [`gesture::on_click`] over [`on_touch_tap`], unless you really want to exclusively
//! touch clicks.
//!
//! [`on_touch_tap`]: fn@on_touch_tap
//! [`on_touch_transform`]: fn@on_touch_transform
//! [`gesture`]: crate::gesture
//! [`gesture::on_click`]: fn@crate::gesture::on_click
//! [`on_mouse_click`]: fn@on_mouse_click
