canvas.getImageData() would have gotten a lot slower as GPU acceleration of Canvas2D became increasingly more common. The initial versions of Canvas2D were all software rasterized, which means getImageData() likely didn't involve any IPCs and definitely didn't involve any GPU readbacks. It was just a memcpy if that.
