Works pretty much the same as Word writer.
Following styles are used for figures:
Figure -- for figure with empty caption
FigureWithCaption (based on Figure) -- for figure with caption
FigureCaption (based on Caption) -- for figure captions
Also, TableCaption (based on Caption) is used for table captions.
We need FigureWithCaption to set keepWithNext, in order to keep caption
with figure.
