Made all RenderTargetView fields non-nullable, and introduced a special Empty value for optional fields. 

This removes the need for a lot of HasValue checks, especially since all fields will eventually get a value anyway, making those checks rather redundant. This also makes it clearer that all SRVs will get bound with a valid input texture, even if the input is optional.
