I have updated a snapshot to CTAN, as part of xpackages. You can 
therefore download xpackages.tds.zip for testing [once Robin has 
installed it, of course :-)].

As Franks says:

the stuff that is implemented (a) should work properly and (b) should 
have a reasonable interface. However, until there is a bit more testing, 
bugs/changes may happen.

Scaling here means 'stretching the content of the box', i.e. 
graphic(s/x)'s \scalebox and \resizebox.
