GTK+ 3.16.3 Updated for GNOME 3.16.2 with Lots of Bugfixes

GNOME 3.16.2 should be out any time now, which means that most of the core components and applications received updates, which leads us to the stable branch of the well-known GTK+ GUI toolkit. GTK+ 3.16.3 is now available for download, and it fixes numerous bugs, among which we can mention an issue with the gdk_set_program_class() function that breaks –class, problems with the HighContrast theme, inverted horizontal sliders, and an xgettext crash on MSYS2.
