/**
* wp.media.controller.GalleryEdit
*
* A state for editing a gallery's images and settings.
*
* @class
* @augments wp.media.controller.Library
* @augments wp.media.controller.State
* @augments Backbone.Model
*
* @param {object} [attributes] The attributes hash passed to the state.
* @param {string} [attributes.id=gallery-edit] Unique identifier.
* @param {string} [attributes.title=Edit Gallery] Title for the state. Displays in the frame's title region.
* @param {wp.media.model.Attachments} [attributes.library] The collection of attachments in the gallery.
* If one is not supplied, an empty media.model.Selection collection is created.
* @param {boolean} [attributes.multiple=false] Whether multi-select is enabled.
* @param {boolean} [attributes.searchable=false] Whether the library is searchable.
* @param {boolean} [attributes.sortable=true] Whether the Attachments should be sortable. Depends on the orderby property being set to menuOrder on the attachments collection.
* @param {string|false} [attributes.content=browse] Initial mode for the content region.
* @param {string|false} [attributes.toolbar=image-details] Initial mode for the toolbar region.
* @param {boolean} [attributes.describe=true] Whether to offer UI to describe attachments - e.g. captioning images in a gallery.
* @param {boolean} [attributes.displaySettings=true] Whether to show the attachment display settings interface.
* @param {boolean} [attributes.dragInfo=true] Whether to show instructional text about the attachments being sortable.
* @param {int} [attributes.idealColumnWidth=170] The ideal column width in pixels for attachments.
* @param {boolean} [attributes.editing=false] Whether the gallery is being created, or editing an existing instance.
* @param {int} [attributes.priority=60] The priority for the state link in the media menu.
* @param {boolean} [attributes.syncSelection=false] Whether the Attachments selection should be persisted from the last state.
* Defaults to false for this state, because the library passed in *is* the selection.
* @param {view} [attributes.AttachmentView] The single `Attachment` view to be used in the `Attachments`.
* If none supplied, defaults to wp.media.view.Attachment.EditLibrary.
