#17 Add SaveAs() to Windows.PlotSurface2D.cs to create a file

[Michael Fitzpatrick]

I am interested in contributing to this project.

Here's a prototype to what I've added so far:

/// <summary>
/// Save as a picture file.
/// </summary>
/// <param name="FilePath">File name.</param>
/// <param name="width">Image width.</param>
/// <param name="height">Image height.</param>
/// <param name="imageFormat">Image format.</param>
/// <returns>True if file saved.</returns>
public bool SaveAsFile(string FilePath, int width, int height,
System.Drawing.Imaging.ImageFormat imageFormat)
{}
