I'm not really sure what the added value of these tests are since we presumably
already have ones for browser actions, which use the same machinery.

But if we don't already have such tests, cool.

Okay, I'll simplify the tests so that it just tries each of the API functions
once and add more specific tests once system indicator-specific behavior is
added.

+chrome.test.runTests([
+  function enableAndDisableNonexistentIcon() {
+    // Disable before enable, just in case.
+    chrome.systemIndicator.disable();
+    chrome.systemIndicator.enable();
+    chrome.systemIndicator.disable();
+    chrome.test.succeed();
+  },

+  //  function setMultiUrl() {
+  //    var multiUrl = { '19': 'sample-19.png', '38': 'sample-38.png'};
+  //    chrome.systemIndicator.setIcon({path: multiUrl}, callback);
+  //  },
+
+  function setImageData() {
+    // Create a canvas, then set the icon using it.
+    var canvas = document.createElement('canvas');
+    canvas.width = 20;
+    canvas.height = 20;
