Hi all,

In Qt 4.3, QtXmlStreamReader was introduced. It is an XML Pull Parser (XPP), 
which is a type of parser that makes it easier to do piecemeal parsing of an 
incoming stream.

It is faster than QtXmlReader and might let us use less KoXmlElements which 
would save memory while parsing.

I'm looking into doing this conversion, probably by first removing all use of 
QtXmlReader and then looking replacing calls like these
  loadOdf(const KoXmlElement &element)
with
  loadOdf(QtXmlStreamReader& reader)
where the reader is positioned at the start of an element.

This is a huge task and I'd like to not endeavor on it without helpful hints, 
so if you have warnings, good advice,  or comforting words, I'd like to hear 
them now.

Cheers,
Jos
