The prefix is for namespacing objects.  Widgets in the GTK+ library use
the GTK+ namespace, and thus begin with Gtk.  Widgets in other libraries
begin with a namespace as appropriate to that library.  Having an object
starting with 'Gtk' doesn't make it a widget -- it just means that it is
part of GTK+.

There are practical reasons for this beyond the 'control' aspect.  Even
widgets that are definitely targeted for inclusion into GTK+ are given
a prefix other than 'Gtk' initially.  This lets applications use both
widgets simultaneously.  As an example, there was a 'GtkComboBox'
developed outside of GTK+ and used in Evolution.  When GTK+ itself got
it's own GtkComboBox, it was not possible to use it with older versions
of evolution.

As a note on those specific examples, GtkDataBox isn't part of GTK+, and
should probably be renamed.  GtkGammaCurve exists mostly as a result of
GTK+ initially being written for the gimp, and would not be let into
GTK+ today.  Putting 'Gtk' in the prefix doesn't make a widget first
class, or magically make it a widget, it just means it's in the GTK+

I think a video widget would be great.  I know of at least one other one
in existence right now (BaconVideoWidget).  However, I don't think
either belongs in GTK+.  Doing so would grow the dependencies of GTK+,
especially when most applications don't need video.
