Clean up a few compiler warnings.

* octave-dock-widget.cc (octave_dock_widget::make_widget):
Correct spelling in comment.

* gl2ps-renderer.cc (draw_pixels): Declare loop variable i as int
to avoid signed/unsigned comparison warning.

* graphics.cc (gtk_manager::do_unregister_toolkit): Change local
variable name to tk_name to avoid shadowing function input.
