Attached:
I've tweaked the context document.

The language in drawFocusRing about closed paths was unnecessary, and 
didn't match
the behavior and code I saw across platforms.

setCaretSelectionRect did account for rotation / skew in the transform 
matrix.
I edited it to allow the UA to provide the AT with a bounding box as 
well as the revised
coordinates.

Following up on the rest of the agenda:

I think we're all in consensus here.

I believe this can be handled by keeping focus on a single element, and
defining its position via drawFocusRing and/or setCaretSelectionRect.

It's not practical to provide positioning information for all content at 
one time;
such information is re-generated programmatically in response to UI events,
such as mouse movement and keyboard input.

Image map proposals for canvas have been turned down in the past.
