Thanks John, I'll work on the revisions.

VPacker and HPacker even doesn't use the transformation explicitly. One of the reason for this was that the size of the Text objects does not depends on the transformation. I guess in most cases, children will have a fixed offset relative to their parent container. Introducing an arbitrary transformation between the child and the parent may make things complicated. On the other hand, the top most container may have its own transformation. In the use case I considered (legend), the size of the box is only known at the drawing time and the offset of the box needs to be calculated on the fly (e.g., using the size of the box and the anchor point). The reason that the offset can be a callable object is to support such situation. As implementing an optional transformation should be trivial, I'll just go ahead an work on it. But it seems not clear to me how to approach this without any specific use case given. > > +ax1.plot([1], label="multi\nline") > > For multi-line|, it appears that we are getting the default "baseline" > vertical alignment but for the legend, 'center' would probably be more > appropriate.

In the current implementation, the baseline of the multi-line text is set to the baseline of the first line. It may not give the perfect center-align, but will give a reasonable results. The other way is to treat the multiline text separately during the packing. But this will need more work as the current Packer class does not know whether its child is multi-line text or not. I'll see what I can do.
