+ * Local directives.

+ *
+ * If you want to set a local directive to single page only, you can add the
+ * prefix `_` (underscore) to directive name. (Spot directives)
+ *
+ * @prop {Directive} backgroundColor Specify background-color style.
+ * @prop {Directive} backgroundImage Specify background-image style.
+ * @prop {Directive} backgroundPosition Specify background-position style. The
+ *     default value while setting backgroundImage is `center`.
+ * @prop {Directive} backgroundRepeat Specify background-repeat style. The
+ *     default value while setting backgroundImage is `no-repeat`.
+ * @prop {Directive} backgroundSize Specify background-size style. The default
+ *     value while setting backgroundImage is `cover`.
+ * @prop {Directive} class Specify HTML class of section element(s).
+ * @prop {Directive} color Specify color style (base text color).
+ * @prop {Directive} footer Specify the content of slide footer. It will insert
+ *     a `<footer>` element to the last of each slide contents.
+ * @prop {Directive} header Specify the content of slide header. It will insert
+ *     a `<header>` element to the first of each slide contents.
+ * @prop {Directive} paginate Show page number on the slide if you set `true`.
+ *     `hold` and `skip` are also available to disable increment of the page
+ *     number.
