ah, I just realized that KSpread misses all of the text-format functionality 
(of text per cell) OOo Calc does support (mainly cause I never was needing 
them for spreadsheets).

re the KSpread::Value and style separation: the current loading code just 
fills a passed QTextCursor what should allow this already. It's more the 
displaying of it that is the problem.

While we are using QTextCursor for it, we depend somewhat on the Layout.(h|
cpp) code in the shapes/text plugin since basic things like underline, link, 
etc. are handled there.

So, if to use the textshape is no way to go, then it may an idea to think 
about moving those drawing/layout/render code from the textshape to kotext 
and allow to reuse it there. Not sure if that makes sense at all...

I guess to duplicate parts of the code isn't a valid theird option here and 
doesn't make sense anyway ;)
