[dependabot-preview]

Bumps winit from 0.20.0-alpha6 to 0.20.0.

Changelog

Sourced from winit's changelog.

0.20.0 (2020-01-05)

• On X11, fix ModifiersChanged emitting incorrect modifier change events
• Breaking: Overhaul how Winit handles DPI:
  • Window functions and events now return PhysicalSize instead of LogicalSize.
  • Functions that take Size or Position types can now take either Logical or Physical types.
  • hidpi_factor has been renamed to scale_factor.
  • HiDpiFactorChanged has been renamed to ScaleFactorChanged, and lets you control how the OS resizes the window in response to the change.
  • On X11, deprecate WINIT_HIDPI_FACTOR environment variable in favor of WINIT_X11_SCALE_FACTOR.
  • Size and Position types are now generic over their exact pixel type.

0.20.0 Alpha 6 (2020-01-03)

• On macOS, fix set_cursor_visible hides cursor outside of window.
• On macOS, fix CursorEntered and CursorLeft events fired at old window size.
• On macOS, fix error when set_fullscreen is called during fullscreen transition.
• On all platforms except mobile and WASM, implement Window::set_minimized.
• On X11, fix CursorEntered event being generated for non-winit windows.
• On macOS, fix crash when starting maximized without decorations.
• On macOS, fix application not to terminate on run_return.
• On Wayland, fix cursor icon updates on window borders when using CSD.
• On Wayland, under mutter(GNOME Wayland), fix CSD being behind the status bar, when starting window in maximized mode.
• On Windows, theme the title bar according to whether the system theme is "Light" or "Dark".
• Added WindowEvent::ThemeChanged variant to handle changes to the system theme. Currently only implemented on Windows.
• Breaking: Changes to the RedrawRequested event (#1041):
  • RedrawRequested has been moved from WindowEvent to Event.
  • EventsCleared has been renamed to MainEventsCleared.
  • RedrawRequested is now issued only after MainEventsCleared.
  • RedrawEventsCleared is issued after each set of RedrawRequested events.
• Implement synthetic window focus key events on Windows.
• Breaking: Change ModifiersState to a bitflags struct.
• On Windows, implement VirtualKeyCode translation for LWin and RWin.
• On Windows, fix closing the last opened window causing DeviceEvents to stop getting emitted.
• On Windows, fix Window::set_visible not setting internal flags correctly. This resulted in some weird behavior.
• Add DeviceEvent::ModifiersChanged.
  • Deprecate modifiers fields in other events in favor of ModifiersChanged.
• On X11, WINIT_HIDPI_FACTOR now dominates Xft.dpi when picking DPI factor for output.
• On X11, add special value randr for WINIT_HIDPI_FACTOR to make winit use self computed DPI factor instead of the one from Xft.dpi.

0.20.0 Alpha 5 (2019-12-09)

• On macOS, fix application termination on ControlFlow::Exit
• On Windows, fix missing ReceivedCharacter events when Alt is held.
• On macOS, stop emitting private corporate characters in ReceivedCharacter events.
• On X11, fix misreporting DPI factor at startup.
• On X11, fix events not being reported when using run_return.
