Similar to commit 798d21e2a1 (tdf#157965:
UNO methods are expected to return sizes in mm/100, 2023-10-29); this
was an omission from commit 9e92a17cb6
(starmath: Improve glyph positioning, 2023-09-19).
The method is called in DomainMapper_Impl::appendStarMath(), and the
returned value is used to define object size using UNO methods.
