		101	=head2 Extension Objects
		102
		103	Every perl extension is a perl class. A separate perl object is created
		104	for each terminal, and each terminal has its own set of extension objects,
		105	which are passed as the first parameter to hooks. So extensions can use
		106	their C<$self> object without having to think about clashes with other
		107	extensions or other terminals, with the exception of methods and members
		108	that begin with an underscore character C<_>: these are reserved for
		109	internal use.
		110
		111	Although it isn't a C<urxvt::term> object, you can call all methods of the
		112	C<urxvt::term> class on this object.
		113
		114	Additional methods only supported for extension objects are described in
		115	the C<urxvt::extension> section below.
		116
		117	=head2 META comments
		118
		119	Rxvt-unicode recognizes special meta comments in extensions that define
		120	different types of metadata.
		121
		122	Currently, it recognises only one such comment:
		123
		124	=over 4
		125
		126	=item #:META:RESOURCE:name:type:desc
		127
		128	The RESOURCE comment defines a resource used by the extension, where
		129	C<name> is the resource name, C<type> is the resource type, C<boolean>
		130	or C<string>, and C<desc> is the resource description.

		372
		373	The event is a hash with most values as named by Xlib (see the XEvent

		1321	Extensions that define extra resources also need to call this method

		1323
		1324	If the method is called on an extension object (basically, from an

		1328	can rename them and get a new set of resources without having to change
		1329	the actual code.
		1330
		1331	This method should only be called during the C<on_start> hook, as there is
