[GSOC] ODS Row height import

[Daniel Bankston]

Hi, Markus,

I was right about some things, and I was wrong about some other things.

XMLTableStylesContext::EndElement() did use ScXMLImport::InsertStyles() 
which used ScTable::SetOptimalHeight() (or something similar) to set the 
row heights.  I used ScDocument::EnableAdjustHeight(false) to prevent 
SetOptimalHeight() from actually doing any work.

ScXMLImport::endDocument() did use ScMyTables::UpdateRowHeights() which 
used ScTable::SetOptimalHeightOnly() to set the row heights for the 
visible sheet and any sheets with tabs.  I removed the call to this 
method, and I removed the method itself since nothing else was using it.

Turns out that the row height was already being imported using UNO.  
ScXMLTableRowContext::EndElement() uses 
XMLTableStyleContext::FillPropertySet() which uses 
ScDocument::SetRowHeightOnly() to set the row height to the imported row 
height values.  This remains.

With these changes, the all unit tests passed and visual inspection of 
the heights appeared correct.  Using my slow debug build on my laptop 
(Intel Core2 Duo T7500 @ 2.20GHz running 32bit GNU/Linux with 3.5GB of 
ram) and the large test file that you gave me, the total load time was 
consistently shorter from 1:48 to 1:37.

I'll push my commits to my feature branch so you can see the changes.

Do you think there is something I am missing here?  For example, will 
there ever be a case where row height is not specified, requiring us to 
calculate the row height?


Respectfully,
Daniel Bankston
