callcatcher: update unused code

Change-Id: Iaaad9302ef8edb47fa95ce8ca608b6f36449521b

Follow logical consequences of the always-NULL.

And, depressingly, big slabs of the IA2 caption code
in writer doesn't actually do anything.

that delete of pWrapPolygon looks dodgy to me

seeing as it is only conditionally replaced later
