// Serves chrome-untrusted://new-tab-page/* sources which can return content
// from outside the chromium codebase. The chrome-untrusted://new-tab-page/*
// sources can only be embedded in the chrome://new-tab-page by using an
// <iframe>.
//
// Offers the following helpers to embed content into chrome://new-tab-page in a
// generalized way:
//   * chrome-untrusted://new-tab-page/image?<url>: Behaves like an img element
//       with src set to <url>.
//   * chrome-untrusted://new-tab-page/background_image?<url>: Behaves like an
//       element that has <url> set as the background image, such that the image
//       will cover the entire element.
//   * chrome-untrusted://new-tab-page/custom_background_image?<params>: Similar
//       to background_image but allows for custom styling. <params> are of the
//       form <key>=<value>. The following keys are supported:
//         * url:       background image URL.
//         * url2x:     (optional) URL to a higher res background image.
//         * size:      (optional) CSS background-size property.
//         * repeatX:   (optional) CSS background-repeat-x property.
//         * repeatY:   (optional) CSS background-repeat-y property.
//         * positionX: (optional) CSS background-position-x property.
//         * positionY: (optional) CSS background-position-y property.
//   Each of those helpers only accept URLs with HTTPS or chrome-untrusted:.
