Fw: drawSystemFocusRing, drawCustomFocusRing

Paul, Janina,

This will give us our second implementation with Firefox support. I will
begin testing it this week.

Rik was also working on a build for webkit which will go into Mac Safari.
This will give us:

Firefox Windows
Chrome Mac
Chrome Windows
Safari Mac

That will more than meet any CR criteria. Furthermore IBM will be
implementing this in our reusable anlytics drawing components which means
MANY IBM products will be using this. Additionally, Pearson is applying
canvas and this feature across their education offerings.

The two APIs: drawCustomFocusRing(element) and drawSystemFocusRing(element)
are NOT at risk.

  Hi Rik,

  Super! Please let me know when it is in the FF nightly. They just started
  FF 28.0a1 nightly a couple days ago.

  When it is I will try it out and provide feedback.

        Hi Rich,

        let me attempt this again today. The issue is not with the path but
        with mozilla's reftest framework that's flaky with setting focus.
        ms2ger posted that there's a way to fix this but I don't know how
        to apply it.

              Hi Rik,

              There is a lot of pressure to get two implementations. How
              soon can you have something in Firefox that I can test with?

              The last time you told me the changes would be in the nightly
              and I tested the nightly but they never showed up.

              We now have the ARIA User Agent Implementation Guide ready
              for last call so I have time to try this out and provide
              feedback.

              Hi Jatinder,

              The drawSystemFocusRing(element) and drawCustomFocusRing
              (element) work in Chrome Canary on Mac and Windows. You can
              run the windows magnifier and it will follow the focus
              location.

              Here are the directions for running with Canary:

              You have to run Chrome with a flag for it to work. You can go
              to chrome://flags and enable "Enable experimental canvas
              features" (and then restart the browser), or else run Chrome
              with the --enable-experimental-canvas-features command-line
              flag.

              Here is the canvas clock example:
              http://www.w3.org/2013/09/accessible_canvas_clock.html

              Here is a sample with two canvas drawn checkboxes that uses
              drawSystemFocusRing():


              (See attached file: CanvasEditor.html)

              I have cc'd Dominic Mazzoni if you have any Chrome specific
              questions.

              As a refresher:

              - Canvas fallback elements are used to maintain a one for one
              mapping to important objects drawn on canvas that must be
              accessible. These fallback elements can be placed in the
              keyboard navigation order and ARIA support may also be
              applied to them to support accessibility
              - The two focus ring API are used to ensure support for
              browser system focus ring conventions and to provide the
              location of the fallback objects on canvas (model view
              controller)

              Regards,


              Rich
