Ethan and I looked at the clipboard a bit.  He wondered if it even makes 
sense to put something in the clipboard of a particular format like PDF, 
or PNG.  I'm starting to wonder that as well.

There is a way to create a PNG type of bitmap and then place that in the 
clipboard.  However, I think this is done by converting that PNG bitmap 
to an internal clipboard BITMAP.

I can create custom data objects to place in the clipboard and assign 
them names like "png", but other programs don't seem to highlight the 
"Paste" text in the menu for a data format like that.  (I.e., the 
calling program doesn't know what a "png" data object is.)

Jun, do you have some program/application in mind that might accept PDF 
from the clipboard?

So, right now the capability is there, but the utility of it is in 
question.  But this brings to mind that HTML is one of the internal 
clipboard formats.  I think I'm going to try figuring out how to place 
and HTML version of the plot in the clipboard along with the BITMAP (it 
can be multiple types of data).  It seems to me that being able to paste 
into an email composer is one of the nicer features, as it means one 
doesn't have to first save the plot to a file, then to email composer.
