`GtkSourceHover` allows a [class@View] to provide contextual information. When enabled, if the user hovers over a word in the text
editor, a series of registered [iface@HoverProvider] can populate a [class@HoverDisplay] with useful information.
To enable call [method@View.get_hover] and add [iface@HoverProvider] using [method@Hover.add_provider]. To disable, remove all registered
providers with [method@Hover.remove_provider].
You can change how long to wait to display the interactive tooltip by setting the [property@Hover:hover-delay] property in milliseconds.
