示例1: DrawTexture

        // test draw pattern
        protected void DrawTexture(CGContext context)
        {
            var destRect = new CGRect (0,0,textureImage.Width,textureImage.Height);
            context.DrawImage(destRect, textureImage.NativeCGImage);

            if (wrapMode == WrapMode.TileFlipX)
            {
                context.ConcatCTM(CGAffineTransform.MakeScale(-1,1));
                context.DrawImage(destRect, textureImage.NativeCGImage);
            }

            if (wrapMode == WrapMode.TileFlipY)
            {
                var transformY = new CGAffineTransform(1, 0, 0, -1,
                                                       textureImage.Width,

                transform = new CGAffineTransform(-1, 0, 0, 1,
                                                  textureImage.Width * 2, textureImage.Height);
                context.ConcatCTM(transform);
                context.DrawImage(destRect, textureImage.NativeCGImage);

                // reset the transform
                context.ConcatCTM (context.GetCTM().Invert());

                // draw one that is flipped by Y axis under the oricinal
                transform = new CGAffineTransform(1, 0, 0, -1,
                                                  0, textureImage.Height);

                context.DrawImage(destRect, textureImage.NativeCGImage);

                // draw the last one of the quadrant which is flipped by both the y and x axis
                context.ConcatCTM (context.GetCTM().Invert());
                transform = new CGAffineTransform(-1, 0, 0, -1,
