Color contrast test incorrect on some font sizes

[timmhayes]

The color contrast tool does not work correctly on fonts that are sized with decimals. I've seen this fail in Chrome with an element that had a size of 10pt, which was rendered at 13.3333px and showed up as a large font that only needs to have a 3.0 contrast ratio.

See a sample of this here:

I looked through your code and found the issue, but it is a problem in the axs.utils.isLargeFont function of the GoogleChome accessibility-developer-tools. So opened this issue for you:
GoogleChrome/accessibility-developer-tools#345

and created this pull request:
GoogleChrome/accessibility-developer-tools#346

I hope it works out for you, since I really like the tool. Thanks!

Same issue here. The extension is throwing "low contrast ratio" fail on fonts which are compiled over 24px and pass the accepted contrast ratio.

My pull request on Google's accessibility-developer-tools has sat unmerged for the last 9 months, so I simply made the change in my local version of tota11y. You can see the unminified changes in Google's repository. I hope that helps.
