"""
ViewBox test cases:
* call setRange then resize; requested range must be fully visible
* lockAspect works correctly for arbitrary aspect ratio
* autoRange works correctly with aspect locked
* call setRange with aspect locked, then resize
* AutoRange with all the bells and whistles
* item moves / changes transformation / changes bounds
* pan only
* fractional range
