New features

• Stabilization of stateless widgets (#1393)
  The old widget API has been completely replaced by stateless widgets (introduced in #1284). Alongside the new API, there are a bunch of new helper functions and macros for easily describing view logic (like row! and column!).

• First-class theming (#1362)
  A complete overhaul of our styling primitives, introducing a Theme as a first-class concept of the library.

• Widget operations (#1399)
  An abstraction that can be used to traverse (and operate on) the widget tree of an application in order to query or update some widget state.

• Lazy widget (#1400)
  A widget that can call some view logic lazily only when some data has changed. Thanks to @nicksenger!

• Linear gradient support for Canvas (#1448)
  The Canvas widget can draw linear gradients now. Thanks to @bungoboingo!

• Touch support for Canvas (#1305)
  The Canvas widget now supports touch events. Thanks to @artursapek!

• Image and Svg support for iced_glow (#1485)
  Our OpenGL renderer now is capable of rendering both the Image and Svg widgets. Thanks to @ids1024!
