104 // TODO(wjmaclean) At some time in the future we may wish to test that a | |
105 // reconstructed layer tree contains the correct linkage for the scroll | |
106 // clip layer. This is complicated by the fact that the json output doesn't | |
107 // (currently) re-construct the tree with the same layer IDs as the original. | |
108 // But, since a clip layer is always an ancestor of the scrollable layer, we | |
109 // can just count the number of upwards hops to the clip layer and write that | |
110 // into the json file (with 0 hops implying no clip layer, i.e. not | |
111 // scrollable). Reconstructing the tree can then be accomplished by passing | |
112 // the parent pointer to this function and traversing the same number of | |
113 // ancestors to determine the pointer to the clip layer. The LayerTreesMatch() | |
114 // function should then check that both original and reconstructed layers | |
115 // have the same positioning with respect to their clip layers. | |
116 // | |
117 // For now, we can safely indicate a layer is scrollable by giving it a | |
118 // pointer to itself, something not normally allowed in a working tree. | |
