Put ofVideoGrabber on ofPlanePrimitive

I haven't been able to piece together this simple exercise: put the video grabber output on a plane.

I have a minimal example. The result is that the plane is the color of the pixel in the top-left corner of the video.

#include "ofApp.h"

//--------------------------------------------------------------
void ofApp::setup(){
    plane.set(ofGetWidth() / 2, ofGetHeight() / 2);
    // nothing I put here seems to help
    plane.setResolution(200, 200);
    vg.initGrabber(ofGetWidth(), ofGetHeight());
}

//--------------------------------------------------------------
void ofApp::update(){
    vg.update();
}

//--------------------------------------------------------------
void ofApp::draw(){
    vg.bind();
    plane.draw();
    vg.unbind();
}

I'm sure I'm missing something basic; but, I've tried many variations here. Thanks for any help.
