[Development] matrix math help needed - https://bugreports.qt.io/browse/QTBUG-84457

[Thiago Macieira]

Neither QMatrix nor QTransform have seen any change since the Qt 5.0 
repository import that was related to the underlying math. Only licensing and 
C++ updates.

The task https://bugreports.qt.io/browse/QTBUG-84457 is claiming there's some 
wrong math or at least unexpected behaviour. Can someone who understands these 
classes take a look?
