/// Interface for interacting with various filters. Interface is defined so that you could create
/// Directx pipelines that involve multiple filters.
///
/// ## Example Usage:
/// ```
/// fn main () {
///     //...
///     let (device, context) = // acquire Device and DeviceContext
///
///     let input_tex = // create an input texture
///     let output_tex = // create an output texture
///
///     // create some directx filter. for example the following
///     let filter = ScaleARGBOrAYUV::new(&input_tex,&output_tex,&device);
///
///     // apply the filter
///     filter.apply_filter(&context);
///
///     // read from the output_texture
/// }
/// ```
