[gimp/gtk3-port: 98/228] app: don't connect to "size-requst" because that's deprecated

[Michael Natterer <mitch src gnome org>]

commit 6fd84de9143dfbeb5cf4d69e0f34c89213f69912
Author: Michael Natterer <mitch gimp org>
Date:   Fri Nov 19 14:00:33 2010 +0100

    app: don't connect to "size-requst" because that's deprecated
    
    Instead, connect to "style-set" and calculate the widget's size
    request there. Also fix the label's offsets after whatever GTK+ text
    drawing changes.
