Specifically in sd/source/core/annotations/Annotation.cxx
We seem to end up fixing leaks here often.
The current tools::JsonWriter API is just very hard to use correctly.
So rather return an OString, which is cheap to copy,
and push that down into the LOK code.
AFAIK that seems to end up requiring less code and less adhoc copying
of data (specifically the queueing code in init.cxx was creating
copies when converting to std::string).
Ideally, we could have some special API to avoid the new strdup()
calls in init.cxx, but not sure how to prevent other people
from accidentally using that.
