// Type definitions for GoJS 1.4
// Project: http://gojs.net
// Definitions by: Barbara Duckworth <https://github.com/barbara42/>
// Definitions: https://github.com/borisyankov/DefinitelyTyped

// A number of types have been declared "any" because they would best be described by a union of specific types,
// not as truly "any" type, and TypeScript does not support union types.  Most of the cases are due to:
//   - a property of type Margin whose setter also accepts a number, for a uniform Margin of that thickness
//   - a property of type Brush whose setter also accepts a string, a CSS color string for a solid color Brush
//   - a boolean property that may also be null (tri-state)
//   - a key type, which may be a string or a number, uniquely identifying a node data within a Model
//   - a property that is string that names a property or that is a function that gets or sets a value, on an Object in a Model
