IMAGINGNET-7502 Implement VectorImage.Create method that provide the ability to create a vector image without specifying its format.

## Create a new vector image, draw some figures and text, and save it into SVG, EMF, WMF, PNG files.

using (SimpleVectorImage image = new SimpleVectorImage(1000, 1000, GraphicsUnit.Pixel))
{
    Graphics deviceContext = new Graphics(image);
    deviceContext.PageUnit = GraphicsUnit.Pixel;

    var brush = new SolidBrush(Color.Yellow);

	deviceContext.FillPie(brush, new RectangleF(10, 10, 80, 80), -270, 270);
	deviceContext.DrawPie(pen, new RectangleF(10, 10, 80, 80), -270, 270);

	deviceContext.DrawArc(pen, new RectangleF(100, 10, 80, 80), 180, 90);

	deviceContext.FillEllipse(brush, new RectangleF(200, 10, 80, 80));
	deviceContext.DrawEllipse(pen, new RectangleF(200, 10, 80, 80));
	deviceContext.FillRectangle(brush, new RectangleF(300, 10, 80, 80));
	deviceContext.FillRectangle(brush, new RectangleF(400, 10, 80, 80));
	
	deviceContext.DrawString("Hello World!", new Font("Arial", 16, FontStyle.Bold), new SolidBrush(Color.Black), new PointF(10, 110));
	image.Save("output.svg", new SvgOptions() { VectorRasterizationOptions = new VectorRasterizationOptions() { BackgroundColor = Color.Empty } });
