Review request for Calligra, Inge Wallin and C. Boemann.


Description
-------

As can be seen e.g. in odf/odt/OpenDocument-v1.1.odt from the calligratests, some OOo versions did not use commas as separators for the offset values in the value "rect(...)" for the attribute "fo:clip". So the parsing fails, for the given document e.g. with
--- 8< ---
KoUnit::parseValue: KoUnit::parseValue: Unit  "cm0cm0cm0cm"  is not supported, please report.
--- 8< ---

And while I created the attached patch with a workaround I changed the code to also:
    * detect "auto" values in rect(...)
    * check number of values in rect(...)
    * handle negative values in rect(...)

Okay to backport to 2.5?
