/**
* Native bindings to the khr_gl_event extension.
*
* 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 {@link org.lwjgl.opengl.ARBCLEvent GL_ARB_cl_event} extension provides the complementary functionality of creating
* an OpenGL sync object from an OpenCL event object.
*
* In addition, this extension modifies the behavior of {@link CL10GL#clEnqueueAcquireGLObjects EnqueueAcquireGLObjects} and {@link CL10GL#clEnqueueReleaseGLObjects EnqueueReleaseGLObjects} to implicitly
* guarantee synchronization with an OpenGL context bound in the same thread as the OpenCL context.
