Aquires this buffer object for using. Only call this method if this buffer
represents a shared object from OpenGL, created with e.g.
Context#bindVertexBuffer(com.jme3.scene.VertexBuffer,com.jme3.opencl.MemoryAccess).
This method must be called before the buffer is used. After the work is
done, the buffer must be released by calling
#releaseBufferForSharingAsync(com.jme3.opencl.CommandQueue)so that OpenGL can use the VertexBuffer again.
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
#acquireBufferForSharingAsync(com.jme3.opencl.CommandQueue) instead.
