Steps to reproduce :

- create a new project
- create a cube
- select the scale tool
- try to scale from the center gizmo and notice that the scale will not be uniform

*Note :
You need to scale a bit a few times to trigger this.
When scaling uniformly with the scale tool using the center gizmo, it will round differently on each axis creating non uniform scales. This is probably not good.
The inaccuracy will grow continuously so it will accumulate over the lifetime of a project if a gmaeobject is scaled and copied many times.
