/*
 * The resourceTable contains a list of wxItemResources (which each may
 * have further children, defining e.g. a dialog box with controls).
 *
 * We need to associate actual windows with each wxItemResource,
 * instead of the current 'one current window' scheme.
 *
 *  - We create a new dialog, create a wxItemResource,
 *    associate the dialog with wxItemResource via a hash table.
 *    Must be a hash table in case dialog is deleted without
 *    telling the resource manager.
 *  - When we save the resource after editing/closing the dialog,
 *    we check the wxItemResource/wxDialog and children for
 *    consistency (throw away items no longer in the wxDialog,
 *    create any new wxItemResources).
 *  - We save the wxItemResources via the wxPropertyInfo classes,
 *    so devolve the code to the appropriate class.
 *    This involves creating a new temporary wxPropertyInfo for
 *    the purpose.
 *
 * We currently assume we only create one instance of a window for
 * each wxItemResource. We will need to relax this when we're editing
 * in situ.
