Use absolute transformation to set location for arrange

Browse source 
Using relative positioning proved to create issues; when spamming of arrange instructions it was possible to end up in the following time line
1: arrange action a is started
2: arrange action b is started
3: arrange action a finished computation, and applies transformations on the models
4: arrange action b finishes computation and applies relative transformations on top of the previous transformations

By using absolute positioning this issue is resolved
