示例1: CreateProjectionMatrix
/// <summary>
/// Creates the projection matrix for the given screen size.
/// </summary>
/// <param name="gl">The OpenGL instance.</param>
/// <param name="screenWidth">Width of the screen.</param>
/// <param name="screenHeight">Height of the screen.</param>

// is, so set it now.
