Comment (by cypherpunks):

 I don't think automatic rounding is sufficient, it tends to give very high
 scores on panopticlick. I think people should be prompted to choose
 between a few very common resolutions (1366x768, 1920x1080, etc) instead -
 this will fit the needs of more users (who want to use tor browser on
 larger screens) while reducing identifying information - on a 1080p
 screen, there are 9 * 5 different sizes a tor browser window could be -
 take out the really tiny ones, and you're still left with a good 20 or 30
 possible sizes. Instead, you could just pick between the five or so most
 popular browser window sizes, as per
 https://hardware.metrics.mozilla.com/. you could even do both - on lower
 security levels, use automated rounding, on higher security levels, pick
 between only a few resolutions.
