I think "snapping" to the closest pixel location is great - and should be the
default (we can still perform anti-aliasing in this case, but by aligning to
the pixel grid we should have a noticeable improvement in quality).
I was also wondering if there is any advantage in quality for performing the
same "snap" for text rendering? Probably only for fonts that are defined with
pixels in mind.
