[whatwg] putImageData() and getImageData()

[Anne van Kesteren]

These features are nice but I don't think authors will understand that  
imagedata.height != canvas.height (likewise for width). Authors will just  
make something that works in their browser and then assume it will work  
everywhere else. Which would horribly break. Even the more experienced  
<canvas> developers playing with these features have already made these  
mistakes.

I'm not quite sure what a good solution to this problem would be.
