* - `altclass` (string): If a file type is unsupported, the end-user will
* see the alt text (above) linked directly to the content. That link
* will have this value as its class name. Defaults to blank.
* - `audio` (string): This is an image that should be used as a
* placeholder for audio files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `bgcolor` (string): The background color for the media, if not
* already transparent. Defaults to `#ffffff`.
* - `height` (integer): The height of the embedded media. Accepts any
* numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `loop` (boolean): Do you want the media to loop when it's done?
* Defaults to `false`.
* - `mediaplayer` (string): The location of the included
* `mediaplayer.swf` file. This allows for the playback of Flash Video
* (`.flv`) files, and is the default handler for non-Odeo MP3's.
* Defaults to blank.
* - `video` (string): This is an image that should be used as a
* placeholder for video files before they're loaded (QuickTime-only).
* Can be any relative or absolute URL. Defaults to blank.
* - `width` (integer): The width of the embedded media. Accepts any
* numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
* and it is recommended that you use this default.
* - `widescreen` (boolean): Is the enclosure widescreen or standard?
* This applies only to video enclosures, and will automatically resize
* the content appropriately. Defaults to `false`, implying 4:3 mode.
*
* Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`
* will default to 480x360 video resolution. Widescreen (16:9) mode with

* Note: for cURL, a minimum of 1 second applies, as DNS resolution

* (float, seconds with a millisecond precision, default: 10, example: 0.01)

* (float, seconds with a millisecond precision, default: 10, example: 0.01)
* - `useragent`: Useragent to send to the server
* (string, default: php-requests/$version)
* - `follow_redirects`: Should we follow 3xx redirects?
* (boolean, default: true)
* - `redirects`: How many times should we redirect before erroring?
* (integer, default: 10)
* - `blocking`: Should we block processing on this request?
* (boolean, default: true)
* - `filename`: File to stream the body to instead.
* (string|boolean, default: false)

* for Basic authentication
* (\WpOrg\Requests\Auth|array|boolean, default: false)
* - `proxy`: Proxy details to use for proxy by-passing and authentication
* (\WpOrg\Requests\Proxy|array|string|boolean, default: false)

* - `hooks`: Hooks handler.
* (\WpOrg\Requests\HookManager, default: new WpOrg\Requests\Hooks())
* - `verify`: Should we verify SSL certificates? Allows passing in a custom
* certificate file as a string. (Using true uses the system-wide root
* certificate store instead, but this may have different behaviour
* across transports.)
* (string|boolean, default: certificates/cacert.pem)
* - `verifyname`: Should we verify the common name in the SSL certificate?

* - `headers`: Associative array of header fields. Same as the `$headers`

* - `cookies`: Associative array of cookie name to value, or cookie jar.
* (array|\WpOrg\Requests\Cookie\Jar)
*
* If the `$options` parameter is specified, individual requests will
* inherit options from it. This can be used to use a single hooking system,
