public function validate(transform:IViewportTransform, target:IViewportTransform):IViewportTransform

Validate the viewport transform by performing transformations until it validates all constraints.

Parameters
transform:IViewportTransform — IViewportTransform object to be validated.
 
target:IViewportTransform — IViewportTransform object that represents the last validated transform.

Returns
IViewportTransform — Validated IViewportTransform object.
