Default dimension for primitive geometry in documentation

Hello,

We can create a QtQuick3D.Model and set some built-in primitives as source: #Cube,  #Rectangle, #Sphere, #Cylinder ...

As far as I saw, there is no indication of the default size for those geometries.
After some experiments, I found out the Cube has a size of 10.

It could be useful to have more information about those default geometries : Size, number of faces (for complex geometry) and so on...
