Winit:

• x11: Destroy dropped windows; handle WM_DELETE_WINDOW - done

  That PR covers:

  • panic after dropping window on X11
  • Dropping Window doesn't close it (X11)

• Support for creating dummy DeviceIds and WindowIds

  This will remove the need for creation of actual windows in some event based testing, e.g. in the application_robot crate.

Amethyst:

• Update to rayon 1.0 - done

RustType:

• Expose font names from std_truetype::FontInfo - done

  Need to wait for rusttype 0.4.2 to be released, and dependencies picking it up. Then the application_ui crate can be updated.
