Text-View width

[Alberto Manuel Brandao Simoes <albie alfarrabio di uminho pt>]

	Hi!

	Like Havoc suggestion, I've made:

gint console_view_get_width(ConsoleView *self, GtkTextTag *tag)
{
    PangoFontDescription *fdesc;
    PangoFontMetrics *metrics;
    PangoContext *context;
    GtkWidget *widget;
    GValue *value;
    int char_width;
    int width_in_chars;

    widget = GTK_WIDGET(self->text_view); 
    context = gtk_widget_get_pango_context (widget);

    g_object_get(tag, "font-desc", fdesc, NULL);
    metrics = pango_context_get_metrics (context, fdesc,
		pango_context_get_language (context));

    char_width = pango_font_metrics_get_approximate_char_width (metrics); 
    width_in_chars = widget->allocation.width / char_width;
    return width_in_chars;
}

But, here's something wrong. The fdesc variable does not contain a correct
font Description!

	Cheers
