[R-SIG-Mac] tiff output on Mac

[David Winsemius]

If you look at:

?png    # you will see several other options

I will say that the advice on that page to use capabilities() to  
determine which of these options is supported seems to be at least  
misleading in that tiff comes back FALSE but the tiff device accepts  
input without complaint and produces output that Preview.app reads.

Another option, ...  handle the translation to a tiff file by using  
Preview of hte saved pdf and then the Grab.app, or just Grab the  
quartz window. That method lets me minimize the white space in the  
margins. Tiff is the saved format from Grab.
