Hi there,

As Stefan Nikolaus has done the first step in decoupling Format from Cell I'm 
about to implement the new Format Storage design as suggested in 
kspread/DESIGN.html

I won't start on it today but plan to dedicate (most of) tomorrow to doing 
this. I cannot yet gurantee that I have time for it (nor to finish it), but 
well, that's what I've planning at least. I hope to get as far as possible. 
If you have any more thoughts on this design, please reply soon.


Some random thoughts of mine:

1) I think we will have rather large grouping of information, that is data 
format, including font, position, ... is one piece, (background) coloring and 
border is another and so on. So I guess we end up with less than 5 layers of 
format pieces. 

2) Row format has a higher priority as column format

3) traversing: I'm not yet sure whether to use a quad tree, but I "guess" not. 

Regards,
