When calculating the node to world transform for use in bounding box queries, cache the values of the transform. In addition, when scroll offsets change, ensure that the cached values are invalided properly. This change necessitated the storage of children for each node in the tree, so that we can walk both up and down the tree. The purpose of this part of the change is to increase performance when doing multiple queries and prepare the tree for hit testing. In addition, this change also tries to take into account sticky offsets, using the algorithm from WebRender to calculate sticky offsets. This is also going to be important for hit testing.
