See [1]. There exists another variable called KDE_SESSION_VERSION, which from
KDE4 on is set to 4, but was not defined for KDE3.x. This can be used further
to distinguish between KDE4 and KDE3.
It seems, for gnome exits GNOME_DESKTOP_SESSION_ID, which can be tested for
exising, although I couldn't find any reliable source for that.
