Steve,

If we have the ability to apply bounds to objects in canvas (the hit
testing API extensions) I could live with what Ian has for
drawSystemFocusRing and drawCustomFocusRing with some tweeks. I mean it is
mostly the Same drawFocusRing divided into two separate APIs. One change
would be to remove the step of observing systems settings for focus ring
style of a custom focus ring. That makes no sense. If an author wants to
create a custom focus ring and not follow system conventions then why have
the step in a custom focus ring? We would be able to gleam the location of
the object from the bounds supplied by setElementPath(Element element) that
Frank was writing up.

Hi all,

HTML Canvas 2D Context Extensions
http://dev.w3.org/html5/canvas-extensions/Overview.html

"This specification extends and overrides the HTML Canvas 2D Context
specification [CANVAS-2D] with additional features for caret and
selection management, for setting the caret blink rate, for returning
the vertical offset of a text anchor point, and for drawing a focus
ring around the current path.

This document is a proposal that is being made available for public
review in order to solicit feedback, particularly from implementors,
with a goal of potential cross-browser implementation and
standardization. "

many thanks to Mike Smith for making this happen.

note: I am acting as editor until someone with the requisite knowledge
steps up.
