In SwNoTxtFrm::PaintPicture() the GraphicObjects are no longer painted
via GraphicObject::Draw() any more there is the problem that they are
not cached any more in the display cache of the GraphicManager; that
used to immediately swap out the Graphic but now they are never swapped
out.  Since there appears to be no use of the GraphicManager's display
cache in the new drawinglayer based rendering path i have no idea how to
swap out the Graphic immediately; instead use the same time-out that
SdrGrafObj is using already.

This timeout is derived from the setting:
Tools->Options->LibreOffice->Memory->Graphics cache->"Remove from memory
after".
