Slint UI library

Release 0.3.3

On December 16 we released Slint 0.3.3, with new features and some bug fixes. Here are the highlights:

• Added support for function, to define helper functions.

  
  CheckBox := Rectangle {
      in-out property <bool> checked;
      in property <string> text;
      public function toggle() {
          checked = !checked;
      }
  
      public function extended-text(ext: string) -> string {
          checked ? text + " " + ext : text
      }
  
      //...
  }
  

• Online editor can now zoom the preview.
• VS Code extension and online editor lets you add and remove bindings from the properties tab.
• Added support for re-exporting types from other files using export * from "./other_file.slint";.
