[HDRI] Photosphere available as Universal

[Greg Ward]

If anyone has one of the new Intel-based iMac's already, please try  
out the Universal version of Photosphere I've posted to  
<www.anyhere.com>.  It's a bit crippled, because it doesn't read or  
write TIFF or OpenEXR files right now, but I'd like to know if it's  
at least working on the Intel.  In particular, I'm curious whether  
you can read your previous catalog file and write it out again  
successfully.

WARNING:  Please make a backup copy of your catalog (*.adb) file  
before trying this out!!

I am not sure I have byte-swapping implemented correctly.  I'm also  
curious if the Intel-based Mac's run the old version of Photosphere  
or not.
