Currently when using the drawWindow or drawImage methods to render scaled bitmaps a resampling method is used that looks almost but not quite like nearest neighbor. (tested on windows and linux) This is very obvious when drawing thumbnails of windows using drawWindow. Text becomes a complete mess and it's very hard to make out even large headers. Reproducible: Always

This bug seems a duplicate of 372462. Additionally, the original bug 98971 does not actually seem fixed, at least for downsized images in 2.0.0.4.

It's possible they could get fixed by the same thing but these are two quite different circumstances that certainly warrant individual attention. I'm moving this to trunk since I don't believe any fix here would make the branch now.

At least in my nightly (20070614), trunk has very pretty resampling - I'd call this fixed in trunk. Sounds like consensus is to punt on any attempt to fix this in 2.* and just focus on 3.0, which is fair.

We can probably just close this as fixed, then, correct?

An issue possibly left here is that linear interpolation downsampling like we're using on most platforms breaks down when you're downsizing by more than a factor of 2. This is a separate issue though and not specific to canvas, there's already bugs on this.
