Outstanding canvas bugs assessment

Léonie, Steve,

Here is my assessment of the Canvas bug list:
https://www.w3.org/Bugs/Public/buglist.cgi?keywords=a11y_canvas%2C%20a11ytf&keywords_type=allwords&resolution=NEEDSINFO&resolution=INVALID&resolution=WONTFIX&bug_status=RESOLVED&product=HTML%20WG&list_id=2000

8722 - close. Canvas now has a drawSystemFocusRing() and
drawCustomFocusRing() . Also the new hit testing functionality for Paths
will allow an AT to zoom into objects providing the author does the binding
between the path and fallback content objects.   Note: the user agent
implementation guide must provide mappings in response to both these
changes.

9061 - close. We are not using this for canvas.

10248 - move to HTML.next. This is Rich Text Editing

10249 - move to HTML.next. This is Rich Text Editing

11240 - move to HTML.next. This is Rich Text Editing

12306 - close: This text exists in the canvas element specification: "When
authors use the canvas element, they must also provide content that, when
presented to the user, conveys essentially the same function or purpose as
the bitmap canvas. This content may be placed as content of the canvas
element. The contents of the canvas element, if any, are the element's
fallback content."

12906 - close: Although the name of the bug refers to not replacing some
input controls with canvas the text of the bug refers to text fields. This
is addressed in the Canvas 2D API specification in section 19 in that it
encourages using canvas for Rich Text Editing. Addressing the accessibility
of Rich Text Editing has been moved to HTML.next13181 - close: We have a
hit testing proposal that includes paths that have been applied to canvas
under the section Hit Regions. This allows an author to route mouse events
to fallback content where the fallback element is bound to a closed path on
canvas. Specifically, the addHitRegion has a control argument which refers
to a fallback content element to which the events would be routed.

14119 - close: This text exists in the canvas element specification: "When
authors use the canvas element, they must also provide content that, when
presented to the user, conveys essentially the same function or purpose as
the bitmap canvas. This content may be placed as content of the canvas
element. The contents of the canvas element, if any, are the element's
fallback content."

11342 - This does not appear to have been addressed by the chairs. We have
focus rings functions but it would be valuable to have this addition to
text metrics in order to compute the path for drawing the focus rings. At
one point they had asked for additional information and it was provided.
