* Add stub for item-edit dialog (for editing properties of an item on double-
  click) -- doesn't actually do anything yet
* Add code to invoke said non-working item-edit dialog on double-click in
  time-value, time-instants and note layers
* Add overlay mode (no text, basic text, all text)

+/* -*- c-basic-offset: 4 indent-tabs-mode: nil -*-  vi:set ts=8 sts=4 sw=4: */
