+/* Notes about the handling of links:
+ *
+ * Links share the GtkLabelSelectionInfo struct with selectable labels.
+ * There are some new fields for links. The links field contains the list
+ * of GtkLabelLink structs that describe the links which are embedded in
+ * the label. The active_link field points to the link under the mouse
+ * pointer. For keyboard navigation, the 'focus' link is determined by
+ * finding the link which contains the selection_anchor position.
+ * The link_clicked field is used with button press and release events
+ * to ensure that pressing inside a link and releasing outside of it
+ * does not activate the link.
+ *
+ * Links are rendered with the link-color/visited-link-color colors
+ * that are determined by the style and with an underline. When the mouse
+ * pointer is over a link, the pointer is changed to indicate the link,
+ * and the background behind the link is rendered with the base[PRELIGHT]
+ * color. While a button is pressed over a link, the background is rendered
+ * with the base[ACTIVE] color.
+ *
+ * Labels with links accept keyboard focus, and it is possible to move
+ * the focus between the embedded links using Tab/Shift-Tab. The focus
+ * is indicated by a focus rectangle that is drawn around the link text.
+ * Pressing Enter activates the focussed link, and there is a suitable
+ * context menu for links that can be opened with the Menu key. Pressing
+ * Control-C copies the link URI to the clipboard.
+ *
+ * In selectable labels with links, link functionality is only available
+ * when the selection is empty.
