Fix on_transform_changed "rounding" transform

Setting `value` without `set_value_no_signal` will trigger
`_on_value_changed` with the rounded values as per the `Step`
value of the `SpinBox`es which in turn updates the transform.

This resulted in small movements when dragging the model with
the mouse to not have any effect.
