Bug 1930230 [wpt PR 49072] - Nearest neighbor images should not use higher quality, a=testonly

Browse Source 
Automatic update from web-platform-tests
Nearest neighbor images should not use higher quality

We recently fixed a bug [1] where the discardable image map was not
preserving image quality values. This fix exposed a bug where nearest
neighbor filtering would incorrectly re-use higher-quality images.
Nearest neighbor filtering is used for `image-rendering: pixelated` and
should not use higher-quality filtering.
