(i didn't test it; this is typically one of the areas where pdf specs
and viewers evolve over time; what works in version 3 viewers may fail
in version 5; normally i adapt that kind of stuff when i run into it /
need it (with the danger of breaking oder stuff); one problem is that
there is a relationship (now) betwene the page where the resource is and
where it is activated [it's that kind of dependencies that has shown
up]; the same for sounds: resources need to be on the same page as where
they are clled (which over time made some examples fail when viewers
changed their expectations).

the rendering mechanism is using the pdf 1.5/6 features i.e. separation
between resource and rendering view (buggy in acrobat 6, but may be
better by now) ; there is some example code in x-res-50 etc

not sure, but overlays are ok (since the undocumented behaviour of
viewers is that the annots end up on top when activated, they have their
own rendering layer (and as a side effect cannot be made invisible in
pdf layers; a typical example of pdf feature creap without forseeing
implicationswhich then needs to be repaired in later pdf specs/viewers)

dunno, if you send me a zip with all resources and a small test file i
can have a look

well, it should go in the widgets manual, but only when the pdf specs is
stable for this; there is some example code in the x-res files (media
libraires and so)
