This action computes transformation matrices for a given subgraph. It computes the cumulative transformation matrix and its inverse, along with a cumulative texture transformation matrix and its inverse.
This action is unlike most others in that it does not traverse downwards from groups. When applied to a node, it computes the matrix for just that node. (This makes sense for transformation nodes, but not for others, really.) It is much more useful when applied to a path. When applied to a path, it gathers the transformation info for all nodes in the path and those that affect nodes in the path, but it stops when it hits the last node in the path; it does not traverse downwards from it as other actions (such as rendering) do. This behavior makes the most sense for this action.
