/**
* Adds contextual links associated with a view display to a renderable array.
*
* This function should be called when a view is being rendered in a particular
* location and you want to attach the appropriate contextual links (e.g.,
* links for editing the view) to it.
*
* The function operates by checking the view's display plugin to see if it has
* defined any contextual links that are intended to be displayed in the
* requested location; if so, it attaches them. The contextual links intended
* for a particular location are defined by the 'contextual links' and
* 'contextual links locations' properties in hook_views_plugins() and
* hook_views_plugins_alter(); as a result, these hook implementations have
* full control over where and how contextual links are rendered for each
* display.
*
* In addition to attaching the contextual links to the passed-in array (via
* the standard #contextual_links property), this function also attaches
* additional information via the #views_contextual_links_info property. This
* stores an array whose keys are the names of each module that provided
* views-related contextual links (same as the keys of the #contextual_links
* array itself) and whose values are themselves arrays whose keys ('location',
* 'view_name', and 'view_display_id') store the location, name of the view,
* and display ID that were passed in to this function. This allows you to
* access information about the contextual links and how they were generated in
* a variety of contexts where you might be manipulating the renderable array
* later on (for example, alter hooks which run later during the same page
* request).
*
* @param array $render_element
* The renderable array to which contextual links will be added. This array
* should be suitable for passing in to drupal_render() and will normally
* contain a representation of the view display whose contextual links are
* being requested.
* @param string $location
* The location in which the calling function intends to render the view and
* its contextual links. The core system supports three options for this
* parameter:
* - 'block': Used when rendering a block which contains a view. This
* retrieves any contextual links intended to be attached to the block
* itself.
* - 'page': Used when rendering the main content of a page which contains a
* view. This retrieves any contextual links intended to be attached to the
* page itself (for example, links which are displayed directly next to the
* page title).
* - 'view': Used when rendering the view itself, in any context. This
* retrieves any contextual links intended to be attached directly to the
* view.
* If you are rendering a view and its contextual links in another location,
* you can pass in a different value for this parameter. However, you will
* also need to use hook_views_plugins() or hook_views_plugins_alter() to
* declare, via the 'contextual links locations' array key, which view
* displays support having their contextual links rendered in the location
* you have defined.
* @param object $view
* The view whose contextual links will be added.
* @param string $display_id
* The ID of the display within $view whose contextual links will be added.

* @see hook_views_plugins()
* @see views_block_view()
