   * #### Font families for 3D SceneViews
   *
   * The supported font families for 3D [SceneViews](https://developers.arcgis.com/javascript/latest/api-reference/esri-views-SceneView.html) are dependent upon the
   * fonts installed on the user's computer and web browser. If an app uses a font that is not installed, the
   * Font class implements a fallback mechanism that will use the default font family value, which is `sans-serif`.
   * See these references for instructions on how to install a new font on [Windows](https://support.microsoft.com/en-us/help/314960/how-to-install-or-remove-a-font-in-windows)
   * or [macOS](https://support.apple.com/en-us/ht201749).
   *
   * Fonts that are not installed locally can also be loaded from a url by defining a [@font-face](https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face)
   * in a css file and referencing it from the `family` property in a symbol layer.
   *
   * #### Font families for 2D MapImageLayer
   *
   * The supported font families for [MapImageLayers](https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-MapImageLayer.html)
   * in a [MapView](https://developers.arcgis.com/javascript/latest/api-reference/esri-views-MapView.html) are dependent upon the fonts installed on the
   * [ArcGIS Server](https://enterprise.arcgis.com/en/server/latest/get-started/windows/what-is-arcgis-for-server-.htm)
   * that published the layer. If an app uses a font that is not installed, the Font class implements a fallback
   * mechanism that will use the default font family value, which is `sans-serif`.
   *
   * #### Font families for 2D FeatureLayer, CSVLayer, StreamLayer, and TextSymbol
   *
   * The supported font families are based on hosted fonts files in `.pbf` format.
   * By default, the fonts available are mostly the same ones used by the Esri Vector Basemaps.
   * These fonts are available via `https://static.arcgis.com/fonts`. The URL can be configured to point to your own font resources
   * by setting the [esriConfig.fontsUrl](https://developers.arcgis.com/javascript/latest/api-reference/esri-config.html#ConfigWithFontsUrl) property. If an app uses a font that is not installed,
   * the Font class implements a fallback mechanism that will use the default font family value, which is `sans-serif`.
   * This uses the `Arial Unicode MS` font file.
