Since we are speaking of libraries, you don't need an instance of the
application to instantiate objects of that library :) It's a little bit like
kross scripts that can be runned without a running instance of a given
application.

No idea, but just try to convert a SVG to a TIFF with koconverter :) And it
uses, krita's tiff filter ;) And I have no doubt that the TIFF export filter of
Krita needs a KisDoc2 as an entry point.
Here is the chain, as I guess it is:
svg -> png (karbon, maybe two steps ?)
png -> KisDoc2 (Krita)
KisDoc2 -> tiff (Krita)
Since the png import filter doesn't create a document, I assume that somewhere,
something in the chain use Krita's KoFactory to create that document instance,
and sounds like it's exactly what KoFilterChain::outputDocument() and/or
KoFilterChain::inputDocument() does.
