Along those lines, and following Alexander's suggestion of not  
including code as attachments, I have placed updated versions of the  
scribble and draggable demos at:


There's also two new demos: an image-view class which does the obvious  
thing, and a pdf-view with overlays, so you can, for example, overlay  
a scribble view over a pdf view and scribble on a PDF.

You'll need to snarf three files from there to run the demos:


The two utils files are intended to be useful in their own right  
independent of the demos.

I have tested these on the heads of the 1.3 and trunk in both 32 and  
64 bit on OS X 10.5.7.  The PDF demo can crash your machine in 64-bit  
mode because of an as-yet uncorrected bug in OS X.

These probably need documentation before they're ready to be included  
in contrib, but they two of the files are public domain and the third  
(rg-utils) just requires attribution so anyone can do pretty much  
anything they like with them.

As always, feedback welcome.
