Description

       This extension enables the function clCreateEventFromGLsyncKHR(3clc).

       This extension allows creating OpenCL event objects linked to OpenGL fence sync objects, potentially
       improving efficiency of sharing images and buffers between the two APIs. The companion GL_ARB_cl_event
       OpenGL extension provides the complementary functionality of creating an OpenGL sync object from an
       OpenCL event object.

       In addition, this extension modifies the behavior of clEnqueueAcquireGLObjects(3clc) and
       clEnqueueReleaseGLObjects(3clc) to implicitly guarantee synchronization with an OpenGL context bound in
       the same thread as the OpenCL context.

       If this extension is supported by an implementation, the string cl_khr_gl_event will be present in the
       CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of param_name values for
       clGetDeviceInfo(3clc).
