Attach the SurfaceTexture to the OpenGL ES context that is current on the calling thread. A
new OpenGL ES texture object is created and populated with the SurfaceTexture image frame
that was current at the time of the last call to {@link #detachFromGLContext}. This new
texture is bound to the GL_TEXTURE_EXTERNAL_OES texture target.
This can be used to access the SurfaceTexture image contents from multiple OpenGL ES
contexts. Note, however, that the image contents are only accessible from one OpenGL ES
context at a time.
\param st A ASurfaceTexture reference acquired with ASurfaceTexture_fromSurfaceTexture()
\param texName The name of the OpenGL ES texture that will be created. This texture name
must be unusued in the OpenGL ES context that is current on the calling thread.
\return 0 on success, negative posix error code otherwise (see <errno.h>)
