I ended up doing something similar drawing Google Map tiles - bypassing the Google Maps API: <a href="http://www.mapfolds.com/2010/11/25/google-maps-on-html5-canvas-grains-on-a-chessboard/" rel="nofollow">http://www.mapfolds.com/2010/11/25/google-maps-on-html5-canvas-grains-on-a-chessboard/</a> Doesn't do the nice wrap-around zoom like yours, but have included some zooming. Nice!

I got it to work in internet explorer -- Well, at least the the internet explorer I have on this computer. I think it's IE 7. I had to do the usual event = !event ? window.event : event for the dragging events and for some reason, I had to make the window.onmousewheel= mouseWheel into this window.onmousewheel = document.onmousewheel= mouseWheel and that finally worked. here's a link to the script with small changes I made http://www.pdxbusiness.com/canvas/slippymap/ What a great script.

Biggest performance isssue is redrawing all tiles when loading images. Other performance issue is drawing a htmlImage which is at least two times slower than data from getImageData or a CanvasHTMLElement. See processingjs.org for an implementation of loadImage.
