Everything that is done by libgksu needs to know a lot of stuff
about what to run, as what user to run and some more information,
as X authentication information and such. All that information is
contained in a GksuContext.

This could be considered one of the main functions in GKSu.
it is responsible for doing the 'user changing' magic calling
the <span class="type">GksuAskPasswordFunc</span> function to request a password if needed.
and the <span class="type">GksuPasswordNotNeededFunc</span> function if a password won't be
needed, so the application has the oportunity of warning the user
what it's doing.
Since 1.3.3.</p>
