Mike, I appreciate you checking this issue out - I have noticed the same thing while testing under Google Chrome & Firefox 3. In fact, Google Chrome, Firefox 3, Safari 4 Public Beta (for Windows), and Opera 9.62 all show only a small difference between the two APIs. Unfortunately I am developing under a requirement to support IE - and the difference in the APIs gets quite ugly as you draw more layers on the new API using IE7 or IE6; however the older APIs function in an acceptable way.
