/* This is intended to serve as a common base class for all HTML viewing
 * needs in Evolution.  Currently based on GtkHTML, the idea is to wrap
 * the GtkHTML API enough that we no longer have to make direct calls to
 * it.  This should help smooth the transition to WebKit/GTK+.
 *
 * This class handles basic tasks like mouse hovers over links, clicked
 * links, and servicing URI requests asynchronously via GIO. */
