/*
* This test tries to approximate the layer structure of
* APZHitTestingTester.ComplexMultiLayerTree from TestHitTesting.cpp.
*
* Notes:
* - The elements are named after the layers in the testcase
* (e.g. "layer1"), but where multiple elements share an APZC,
* new elements named "scroller1" etc. are introduced to be
* the scroll containers.
* - overflow: hidden is used to avoid spurious scrollbar layers.
* To trigger APZC creation, the test code explicitly sets display
* port margins.
* - Perspective transforms are used to force an element to be
* layerized if it otherwise wouldn't.
* - One difference is that the entire contents of the APZC that
* scrolls layer{4,6,8} is shifted to the right by 100px.
* Otherwise, the dimensions of the layers make it such that
* this APZC's composition bounds covers up layers{1,2,3}
* and those cannot be hit.
