The WithData method of the Texture2DBuilder class allows you to specify the raw byte data for a texture. This method is part of a fluent interface, enabling you to chain multiple configuration methods together to build a texture with specific properties.

To use the WithData method, you need to provide a byte array that contains the texture data. This method returns the Texture2DBuilder instance, allowing for method chaining.

Example usage:

var textureBuilder = new Texture2DBuilder();
textureBuilder.WithData(myTextureData)
              .WithSize(256, 256)
              .WithFormat(ImageFormat.RGBA8)
              .Finish();

In this example, myTextureData is a byte array containing the texture data. The texture is configured to be 256x256 pixels with an RGBA8 format, and then the Finish method is called to create the texture.
