iOS: Dpi overhaul (#1223)

* WIP - Make EL2 DPI changes and implement on Windows (#895)

* Modify DPI API publicly and on Windows

* Add generic Position and make dpi creation functions const

* Make examples work

* Fix fullscreen windows not appearing

* Replace Logical coordinates in window events with Physical coordinates

* Update HiDpiFactorChanged

* Document to_static

* On Windows, make AdjustRect calls DPI-aware when possible (#1015)

* Use AdjustWidowRectExForDPI when available

* Prioritize presevering logical size when handling WM_DPICHANGED

* Format

* Add changelog entry

* macOS: Dpi overhaul (#997)

* WIP - Make EL2 DPI changes and implement on Windows (#895)

* Modify DPI API publicly and on Windows

* Add generic Position and make dpi creation functions const

* Make examples work

* Fix fullscreen windows not appearing

* Replace Logical coordinates in window events with Physical coordinates

* Update HiDpiFactorChanged

* Document to_static

* fix app_state errors

* fixes hidpi related errors in window_delegate

* fix bad merge

* dpi_factor edits in window_delegate

* fixes type and lifetime errors in window and window_delegate

* applies fmt

* complies with @aleksijuvani requested changes

* modifies Handler lifetimes

* fixes lifetime isues, adds propper handling for HiDpiChanged

* applies fmt

* restore original lifetimes

* solution is somewhere out there

* applies fmt

* pass as references

* resolves issue with HANDLER

* crate visible type error

* fixes visibility issues

* applies fmt

* deals with warnings

* simplifies new_inner_size setting algorthm

* moves proxy instead of referencing it and removes double deref from proxy.ns_window

* makes @Osspial tests (https://github.com/rust-windowing/winit/pull/997\#discussion_r301852354) pass

* complies with @aleksijuvani suggested changes

* makes max window size std::f32::MAX

* On Windows, fix new DPI API not setting window size properly (#1130)

* First attempt

* Second attempt

* Maintain cursor horizontal ratio

* Fix DPI change handling when maximized

* Revert window example

* Make new DPI code more understandable

* Format

* Implement DPI Usability Upgrades for X11 and Wayland (#1098)

* Fix compile errors

* Use `mio` for the X11 event loop

* Removes `calloop` from the X11 event loop, as the method of draining a
  source using a closure provided to the `calloop::EventLoop` instance
  conflicts with the need to deliver events directly to the callback
  provided to `EventLoop::run`, in order to respond to the value provided by
  `WindowEvent::HiDpiFactorChanged`.

* Implement interactive `HiDpiFactorChanged` event for X11

* Implement interactive `HiDpiFactorChanged` event for Wayland

* Run cargo fmt

* Fix Wayland not processing events from EventQueue

* Backport #981

* some lifetime tinkering

* finishes lifetime tinkering

* fixes all type errors

* adds support ffi functions

* adds wrappers for nonstatic events

* replaces events with event wrappers

* reimplementing hidpichanged event in app_state

* implements HiDpiFactorChanged for iOS

* applies formatter

* complies with @aleksijuvani requested changes

* resolves conflicts

* applies fmt

* removes merge blurp

* corrects state of CHANGELOG

* fix fmt check error

* fixes hidpi_factor for armv7-apple-ios
