Paper size is one I remember right now. Another is the location of
Ghostscript.
How about adding some code to `openp' so that, on w32 platforms, it
would look for the program/file in the Registry, in addition to the
list of directories it gets as its argument?
Where do you look? This is the first time I have ever heard of looking
for a path in the registry. You'd need to have a mapping of known
programs to where they store their registry key telling you where their
path is. There is no standard for doing this!
HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\.
There you will find for example a key named firefox.exe under which you
find the actual path to firefox.exe. But you are right, not all programs
use this, unfortunately. So in many cases you need a more specific mean
to get the path, but it is still often in the Registry.
