// SDisplayCore implementation that uses WMHooks to capture changes to
// the display.
// Whenever changes are detected, the SDisplay's updateEvent is signalled,
// so that it can perform housekeeping tasks (like ensuring the currently
// active desktop is the correct one), before flushing changes from the
// Core to the VNC Server. The SDisplay will clip the changes before they
// reach the VNC Server.
