QHighDpiScaling: ABI compatibility broken between 5.13.2 and 5.13.0

We have built our application against 5.13.0 and are in need of a corrected feature from 5.13.2. When replacing the DLLs an error popped up:
 

---------------------------Test.exe - Entry Point Not Found---------------------------The procedure entry point ?factor@QHighDpiScaling@@SANPBVQWindow@@@Z could not be located in the dynamic link library Test.exe.---------------------------OK   ---------------------------

Note that the DLL name and the name of the executable are the same.

Upon closer inspection of QHighDpiScaling class it was noticed, that some static functions named "static qreal factor(...)" of the public interface have been replaced by a template function that may lead to this behaviour.
