Description about the properties of visibleArea is ambiguous

https://doc.qt.io/QtForMCUs-2.4/qml-qtquick-flickable.html

It's not clear what heightRatio, widthRatio, xPosition and yPosition do in the documentation.

I assigned some value to them, tried to output them and even read the code in order to understand them but still cannot understand what they do and what they are for.

Now, since even I, someone inside Qt, is struggling to understand them, it's highly likely that some of our customers will too, someday in the future.

I want to reduce the frustration of the usrs as much as possible, so could you elaborate on these properties in the documentation?
