/**
* Native bindings to the intel_accelerator extension.
*
* The accelerator extension consists of a unified set of OpenCL runtime APIs to create, query, and manage the lifetime of objects which represent
* acceleration processors, engines, or algorithms. Accelerator object instances are referenced with the generic cl_accelerator_intel type by the runtime
* API, but they are always associated with a specific acceleration engine type, which is assigned by the application at accelerator object creation time.
* Descriptors are used to assign acceleration engine-specific properties to the accelerator objects. This mechanism of specialized creation with generic
* referencing is analogous to the way image objects are managed in the OpenCL 1.2 runtime API via generic cl_mem referencing but specialized
* descriptor-based creation with {@link CL12#clCreateImage CreateImage}.
*
* Each accelerator object is assigned a unique type id. Vendors are freely encouraged to define new accelerator types and ids. This base extension
* provides unified mechanism for the creation and lifetime management of new accelerator types, but the semantics and creation descriptors of these types
* are to be defined in acceleration engine-specific extensions.
*
* Accelerator objects can be supplied to kernels as arguments. Unless an extension defines a new OpenCL C language type for the engine-specific
* accelerator (e.g. sampler_t), accelerator objects can only be used in conjunction with built-in kernels. If an extension does define such a new type,
* or if it provides a mechanism to access accelerator data within kernels, then accelerator objects can act as regular kernel arguments as well.
*
* Requires {@link CL12 CL12}.
