/***************************************************************************/
/* The target-testing and pop-frame-filling functions in this section
come in sets, which define and implement classes of pop-frames
(whether those be popups, or popins, etc.). (These classes are things
like “a link that has a statically generated extract provided for it”,
“a link to a locally archived web page”, “an anchorlink to a section of
the current page”, and so on.)
Each set contains a testing function, which is called by
testTarget() to determine if the target (link, etc.) is eligible for
processing, and is also called by fillPopFrame() to find the
appropriate filling function for a pop-frame spawned by a given
target. The testing function takes a target element and examines its
href or other properties, and returns true if the target is a member of
that class of targets, false otherwise.
NOTE: These testing (a.k.a. “type predicate”) functions SHOULD NOT be used
directly, but only via Extracts.targetTypeInfo()!
Each set also contains the corresponding filling function, which
is called by fillPopFrame() (chosen on the basis of the return values
of the testing functions, and the specified order in which they’re
called). The filling function takes a target element and returns a
DocumentFragment whose contents should be injected into the pop-frame
spawned by the given target.
