Looking for people using getImageData already, I find:
http://canvaspaint.org/paint.js - incorrect (though commented out)
http://svn.sourceforge.net/viewvc/jsmsx/trunk/msx.js?view=markup - incorrect
http://www.thescripts.com/forum/thread521112.html - incorrect
http://tech.groups.yahoo.com/group/canvas-developers/files/buttons.html
(or maybe <http://f1.grp.yahoofs.com/v1/gORFRoOLlxuXtJddXwdSyravD-aFfgNuYoSzjI8vUevuBxus3V1sXs5xckiHKd1osiUpDE_bku-vtGMFPV_M-2JZkLKXTqc/buttons.html>)
- correct
I couldn't find any others doing anything with the
ImageData.width/height, but three of those four will break when
somebody implements getImageData with imagedata.width != canvas.width.
