I've revamped the internal imports, and so it now compiles under DMD 0.163.  In the process, I've got rid of most public imports between modules - those that remain are in smjg.libs.sdwf.all and the new smjg.libs.sdwf.core.  So you might need to tweak your own imports so that your code still compiles.

And some stuff has been added to TreeView to facilitate handling of user editing of item text.
