/// Create a GDI Compatible TextLayout. Takes a string, format, and associated constraints, and produces an object representing the result, formatted for a particular display resolution and measuring mode.

/// The resulting text layout should only be used for the intended resolution, and for cases where text scalability is desired {{CreateTextLayout}} should be used instead.

/// <param name="text">An array of characters that contains the string to create a new <see cref="T:SharpDX.DirectWrite.TextLayout" /> object from. This array must be of length stringLength and can contain embedded NULL characters. </param>
