// Handles for non-dispatchable objects are either pointers, or arbitrary

// the object even in a null driver. For the rest, we form a handle as:
//   [63:63] = 1 to distinguish from pointer handles*
//   [62:56] = non-zero handle type enum value
//   [55: 0] = per-handle-type incrementing counter
// * This works because virtual addresses with the high bit set are reserved
// for kernel data in all ABIs we run on.
//
// We never reclaim handles on vkDestroy*. It's not even necessary for us to
// have distinct handles for live objects, and practically speaking we won't
// ever create 2^56 objects of the same type from a single VkDevice in a null
// driver.
//
// Using a namespace here instead of 'enum class' since we want scoped
// constants but also want implicit conversions to integral types.
