This method must be called before the buffer is used. After the work is
done, the buffer must be released by calling

The generated event object is directly released.
This brings a performance improvement when the resource is e.g. directly
used by a kernel afterwards on the same queue (this implicitly waits for
this action). If you need the event, use
Buffer.acquireBufferForSharingAsync(com.jme3.opencl.CommandQueue)
instead.acquireBufferForSharingNoEvent
