Cropped pixels on rotation

It'd be great if you could come up with an example if you're going to file an issue. I guess you mean something like this?

var img = {
  width : 8, height : 8, bpp : 8,
  buffer : new Uint8Array([
    3,3,3,3,3,3,3,3,
    3,3,3,3,3,3,3,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,3,3,3,3,3,3,3,
  ]).buffer
};
g.drawImage(img,4,4,{rotate:Math.PI});

It definitely feels like there is some kind of issue there - seems to be missing at least the right and bottom edge...
