Xwt.Context.DrawImage prevents further painting (GTK backend) about xwt

[luiscubal]

The following code reproduces the issue on my Linux Ubuntu system.

using System;
using Xwt;
using Xwt.Drawing;

namespace BugTest
{
    public class Program : Xwt.Canvas
    {
        public static void Main() {
            Application.Initialize();

            var win = new Window();
            win.Size = new Size(200, 200);
            win.Content = new Program();
            win.Show();

            Application.Run();
        }

        private Image myImage;

        public Program() {
            myImage = Image.FromFile("foo.png");

            Show();
        }

        protected override void OnDraw (Context ctx)
        {
            base.OnDraw (ctx);

            ctx.SetColor(Color.Black);
            ctx.Rectangle(new Rectangle(0, 0, 100, 100));
            ctx.Fill();

            //ctx.Save();
            ctx.DrawImage(myImage, new Point(0, 0));
            //ctx.Restore();

            //ctx.SetColor(Color.Black);
            ctx.Rectangle(new Rectangle(64, 64, 32, 32));
            ctx.Fill();
        }
    }
}

The weird part is that, just like Save()/Restore() can be used to fix the issue. Uncommenting the second SetColor call also fixes the problem.

Seems to be fixed now.
