I realize that in practice they can be non-integral, but are callers OK with fractional values here? 97851 1 bzbarsky 2013-12-23 05:24:06 +0000 Similar for outerWidth/Height too. 106422 2 zcorpan 2014-05-20 05:19:54 +0000 Some information from Rossen from Microsoft regarding MouseEvents: [[ [13:56] <Rossen_> here's an example content that will break from sub-px values [13:56] <Rossen_> for (var x = startX; x != (endX + xDir); x += xDir) ... [13:57] <zcorpan> thanks. do you have a URL also= [13:57] <Rossen_> In this case, xDir is a direction, so -1 or 1. startX is where the mouse clicked down, and the endX is where the mouse is currently, as reported in the offsetX to the mouseMove handler. The problem is, this script assumes you will only return integer values for offsetX and it does a != check rather than < or >. Chrome only reports integers, so there's no problem. They also have a special workaround for Firefox, who doesn't even define offsetX [13:58] <Rossen_> http://goosecode.com/shapdar [13:59] <Rossen_> If you were to return fractional values here, this for loop goes on forever and it would hang. I think the only thing to do here is outreach to the site. [14:09] <zcorpan> is it ok if i make this information available in a public place? [14:11] <Rossen_> for sure ]] 106454 3 rbyers 2014-05-20 15:51:01 +0000 Note that we're attempting to ship at least sub-pixel scroll offsets (and also width/height) in blink in http://crbug.com/360889.
