 and 64-bit integer value can coexist in one array one next to the other. In the both cases, when the one address
 has its own dedicated storage class and the other is regular integer, the shader is responsible for how to interpret
 and use input addresses. Regardless of the shader, the application always passes them as 64-bit integers.
