Maciej, I created a Change Proposal to address the separation of DrawFocusRing into two methods and provided additional information pertaining the chairs had requested for text baseline. I tried to use as much as I felt was correct from the changes Ian made to the WhatWg spec., including the way he allowed for AT to be integrated with the browser as we will see with Chrome going forward. I felt there were some problems with Ian's spec. which I did not enumerate as the change proposal is written against the W3C spec.: - He assumed that all fallback contented needed to support the canvas element would need to be descendant of the canvas element. There will be times, such as hidden context menus, where content may reside hidden at the end of the DOM as transparent fallback content. - Ian's change still allowed the condition in drawCustomFocusRing such that if a system setting was not available to draw a focus ring in a certain style that the function could return allowing the author to create a new path for the focus ring with different styling. The new path may not match the path passed to browser and thus the magnification solution - drawCustomFocusRing should draw a custom focus ring and not adhere to system settings for styling as it is a custom focus ring. We have provided a drawStandardFocusRing function. Please provide feedback before take this to a more formal change proposal submittal. Charles Pritchard tried to get Ian to give feedback on the changes to DrawFocusRing on the WhatWg discussion list for weeks but received no response. http://www.w3.org/html/wg/wiki/ChangeProposals/FocusRingTextBaseline Thanks you, Rich Rich Schwerdtfeger CTO Accessibility Software Group
