Is the zip file a patch or does it just show the issue?

Just shows the issue.  Sorry.  I've been swamped and haven't had time to dig 
into 
this myself (not to mention it's a bit over my head).  Thanks.

Can you retry this with revision 60. I believe it is working correctly now.

Sorry to say there is no change in any of the use cases with revision 60.  All 
are 
reacting exactly the same as stated above.

Also, my original report states that the issue is reproducible with test case: 
/testcases/overflow.html.  That is incorrect.  This should have read: 
/testcases/drawimage.html.

I also have experienced the non-rotation problem in IE8 on Windows XP.

The code works as expected in IE7 on Vista.

Please see http://www.browserpilot.com/canvascompass.php  for an example.  
Press "Rotate" to begin or end the rotation.

I've had trouble with rotating image as well
removing <!DOCTYPE ...> helped. Still trying to find out how.
