- otherwise we might end up with wrong coordinates
 - fixes fdo#38580

it is in the main installation tarball anyway; it was put in langpacks
that did not have its own dictionary from some strange reason

Turns out that this change affected all cppunit runs.

Without manually releasing the EditDLL singleton instance, it gets
deleted *after* the cppunit does its cleanup, which de-initializes VCL.
The problem is, when the EditDLL instance is destroyed, its member
GlobalEditData instance deletes the OutputDevice instance that it owns,
which in turn accesses font caches in VCL.  But by the time we reach
that point, VCL is already de-initialized, hence the problem.

It has been replaced by SheetDataBuffer.

Actually this is a bit more tricky. Currently it is showing wrong values
for hidden rows/columns

Otherwise the normal linear search should be sufficient.  Eventually
we need to use a better algorithm here than this special case handling...

But instantiating EditEngine causes segfault.  The line is commented
out for now.

- Remove using older properties to get errorbars data.
- Only export X errorbars when using ODF VERSION >= 1.2.
- Use the dimension attribute to set errorbar direction.

- Add method to calculate X standard deviation.
- Set correct XErrorBar position when using standard deviation error
type.
