properties-changed and notify signals

[Eric Lemings <eric b lemings lmco com>]

Howdy,

I searched through the mailing list archives and was suprised to find
that this topic was not in already there.  I could swear somebody has
asked this question before.  If I missed it somehow, just direct me
there.

What's the difference between the properties-changed and notify signals
in GObject?  And why do the "set" functions emit both signals while the
"notify" function only emits the properties-changed signal?

Eric.
