Would be nice ( even better if we can support header
and footer)

Supporting group in Writer can also be nice...

I tried to add limited support for charts for
Spreadsheet, but this is very complicated
( and I am not fully sure that I have chosen the good
interface ) ;
note that this also implied to add support to create
formula, ...

Can be nice, but I do not know if this is really
important…
In fact, when I last worked on libodfgen, I added code
to export settings in all generators
( but mainly to make these classes behaviors more
identical )

Normally, these functions have already been dropped.
But this problem is more general, i.e. we have many
define functions, some are implemented,
but I am not sure that all these functions are
implemented ...

We would probably need to add it latter, but not now (
and this seems a very complex task )
Potential ideas:
. Is it better if we make all interface inherit from a basic
generic interface ?
. Do we need to add some numbering styles interfaces in text, …
(i.e. functions which allows to define
a number/date/time format ) ? Idem for formula
. If the interface for presentation need also chart, do we need
to add a RVNGChartInterface and some
mechanism to obtain access to this interface in
RVNGPresentation/SpreadsheetInterface
