The function ```
get-constraints
```

returns the constraints for *
element*
as multiple values (the values are the minimum width, the minimum height, the maximum width and the maximum height).

This function calls the generic function calculate-constraints to calculate these sizes initially, but then just uses the values in the geometry cache for the element. To force an element to take account of its new constraints, call the function invalidate-pane-constraints.
