Fields is a bitmask indicating which members of the DEVMODE
are significant for a particular operation.  Use a bitwise or of win32con.DM_*
flags.  print_desktop.py in the demos directory uses it.

These functions can certainly be added.  It will take some extra work
(the usual LoadLibrary/GetProcAddress thing) since many of them
don't exist on WinNT.  You can submit a feature request (or patch)
on SourceForge: http://sourceforge.net/projects/pywin32/
