[Libreoffice] [REVIEW] Proper initialization and copying of union matrix value.

I'd like to commit the attached patch to the 3.4 branch.  This was
discovered by the unit test which failed when an empty matrix element
didn't have a value of 0.0.  As it turned out, I was initializing the
higher 4 bytes via 32-bit pointer but the lower 4 bytes were left
un-initialized, which caused the double value to become non-zero.
Apparently this doesn't happen when building a 64-bit build.

Thanks,

Kohei
