private boolean contains( Component c, int x, int y ) {

Same as {@link Component#contains(int, int)}, but not using that method
because it may be overridden by custom components and invoke code that
tries to request AWT tree lock on 'AWT-Windows' thread.
This could freeze the application if AWT tree is already locked on 'AWT-EventQueue' thread.
