/** An overview of how a new SwTextFlyCnt is created:
* MakeTextAttr() is called e.g. by SwTextNode::CopyText().
* The following steps are required to clone:
* 1) copying the pFormat with content, attributes etc.
* 2) setting the anchor
* 3) notification
* Because not all required information is available at all times,
* the steps are distributed variously:
* ad 1) MakeTextAttr() calls DocumentLayoutManager::CopyLayoutFormat()
* which creates the new SwFlyFrameFormat and copies the content of the
* fly frame.
* ad 2) SetAnchor() is called by SwTextNode::InsertHint() and sets the anchor
* position in the SwFlyFrameFormat to the SwPosition of the dummy
* CH_TXTATR_BREAKWORD. This cannot be done in MakeTextAttr() because it
* doesn't know the target text node.
* ad 3) GetFlyFrame_() is called during text formatting by SwTextFormatter
* and searches for the SwFlyFrame for the dummy char of the current
* SwTextFrame. If none is found, a new SwFlyInContentFrame is created.
* Important: pTextFrame->AppendFly() immediately triggers a reformat
* of pTextFrame. However, the recursion is blocked by the lock mechanism
* in SwTextFrame::Format().
* The advantage of all this is that it's not necessary to explicitly iterate
* over all SwTextFrames that depend on the SwTextNode to create the
* SwFlyInContentFrame - this is done automatically already.
