strip now obsolete comment part
... but keep the SdrDelayBroadcastObjectChange as it still serves during
copying notes/captions.

sc-perf: lock drawing layer during creation of captions for Save
This gives an extra boost compared to commit
451c4cccc7e3ec3f1e046d3232cb52f6fc443f59 (see there for further details)
as it eliminates broadcasts to accessibility and thus obtaining text
forwarders
and what not.
ScPostIt::CreateCaptionFromInitData() compared to that commit
from 145,055,889,118
to 63,386,691,509
Overall ScDocShell::SaveXML() from original state before that commit
Before: 370,433,720,090
After: 107,468,180,524
Reduced to 29% or speed-up by factor 3.45
