// * This enumerated value can be specified as part of the <properties> argument passed to clCreateContext
// * to allow OpenCL compliant devices in an existing CGL share group to be used as the devices in
// * the newly created CL context. GL objects that were allocated in the given CGL share group can
// * now be shared between CL and GL.
// *
// * If the <num_devices> and <devices> argument values to clCreateContext are 0 and NULL respectively,
// * all CL compliant devices in the CGL share group will be used to create the context.
// * Additional CL devices can also be specified using the <num_devices> and <devices> arguments.
// * These, however, cannot be GPU devices. On Mac OS X, you can add the CPU to the list of CL devices
// * (in addition to the CL compliant devices in the CGL share group) used to create the CL context.
// * Note that if a CPU device is specified, the CGL share group must also include the GL float renderer;
// * Otherwise CL_INVALID_DEVICE will be returned.
// *
// * NOTE: Make sure that appropriate cl_gl.h header file is included separately
