Good point - I believe they were needed for Firefox 2.0 and pre-release 
versions of Opera 9.5 in order to get sensible results in test cases 
that weren't designed to be testing getImageData, but all modern 
browsers implement getImageData correctly so it shouldn't be necessary. 
I've changed my local copy now so it simply calls the function with no 
extra workarounds (though I won't update the online copy until I've 
tested it more carefully).
