<div class="im">Gecko will scale canvas images in one of two
ways: either using a nearest-neighbor algorithm or using a more
complicated (bilinear, bicubic, may depend on other details) algorithm
which is slower but usually gives better results. You can control
which is happening by setting mozImageSmoothingEnabled on the canvas 2d
context (set to false to get nearest-neighbor and set to true to get
the other).<br>
<br>
The default value there is true. Does setting it to false give you the
Chrome 6 behavior, perchance? I'd be a little surprised if it does,
but worth trying.<br>

Forgive me as I have not kept up with all the discussions on this list,
but have there been any suggestions with regards to NOT using a filter
for rescaling? That would be ideal for 'old-skool' graphics where
pixellation is actually desired, not smoothing.<br>
