New features

• Canvas interactivity (#325)
  A trait-based approach to react to mouse and keyboard interactions in the Canvas widget.

• iced_graphics subcrate (#354)
  A backend-agnostic graphics subcrate that can be leveraged to build new renderers.

• OpenGL renderer (#354)
  An OpenGL renderer powered by iced_graphics, glow, and glutin. It is an alternative to the default wgpu renderer.

• Overlay support (#444)
  Basic support for superpositioning interactive widgets on top of other widgets.

• Faster event loop (#597)
  The event loop now takes advantage of the data dependencies in The Elm Architecture and leverages the borrow checker to keep the widget tree alive between iterations, avoiding unnecessary rebuilds.

• Event capturing (#614)
  The runtime now can tell whether a widget has handled an event or not, easing integration with existing applications.

• PickList widget (#444)
  A drop-down selector widget built on top of the new overlay support.

• QRCode widget (#622)
  A widget that displays a QR code, powered by the qrcode crate.
