    Will this help with “crisp” rendering when scaling up an image? I.e. can I avoid anti-aliasing, and get nearest neighbor for example?

    Use: I have a checkerboard that has “cells” that are multiple pixels on a side, 10×10 say. A fast rendering stunt is to build a small, 1×1 image via ImageData and scale it up by 10. But I need to avoid anti-aliasing.

    Currently I have to set:
    ctx.imageSmoothingEnabled = false
    ctx.mozImageSmoothingEnabled = false
    ctx.webkitImageSmoothingEnabled = false
    … and pray that it works.
