20:20:56 [richardschwerdtfe]
      Frank: I would like to discuss the 3 bullets
20:22:07 [richardschwerdtfe]
      Frank: So the user can tab into the canvas control and the author is
      responsible for doing the drawing
20:23:26 [richardschwerdtfe]
      jcraig: You mention that HTML rendering should be such elements
      should be rendered as part of the HTML navigation order
20:24:19 [richardschwerdtfe]
      jcraig: we should state that this be rendered the same as normal HTML
      althought invisibly to allow the author to place elements according
      to their postion on the canvas
20:25:31 [richardschwerdtfe]
      Frank: I would like the 3 bullets to refer to the author
20:25:42 [richardschwerdtfe]
      Frank: what about the canvas API used?
20:25:53 [richardschwerdtfe]
      Rich: The canvas API was removed from the HTML spec.
20:28:05 [richardschwerdtfe]
      jcraig: The last bullet point is problematic as there is no such
      setting
20:28:21 [richardschwerdtfe]
      jcraig: Isn't that there is a detection of background images
20:28:38 [richardschwerdtfe]
      jcraig: it is non standard
20:29:49 [richardschwerdtfe]
      Rich: I don't like to leave the impression that the author does not
      need to address font and color changes
20:30:03 [richardschwerdtfe]
      Cynthia: It can be done using a style sheet
20:30:16 [richardschwerdtfe]
      jcraig: the author could create author styles
20:30:53 [richardschwerdtfe]
      jcraig: if the high contrast color was on and we had style sheet,
      javascript can detect that
20:32:27 [richardschwerdtfe]
      cynthia: I could request a feature to detect the high contrast
      settings
20:33:16 [richardschwerdtfe]
      jcraig: An API that is going to be rendered would need to detect
      system settings for color settings and then adapt the color
20:35:06 [richardschwerdtfe]
      Rich: we would need to impact the drawing using a collection of
      properties
20:35:31 [richardschwerdtfe]
      Rich: You could simply change your color paletted that limited line
      drawing and text drawing to specific colors
20:36:28 [richardschwerdtfe]
      Cynthia: would it be better to have apis to get the system settings?
20:36:54 [richardschwerdtfe]
      jcraig: we could still rely on the author setting the colors
20:37:43 [richardschwerdtfe]
      Cynthia: authors are required to pickup system visual settings
20:38:14 [richardschwerdtfe]
      http://lists.w3.org/Archives/Public/public-canvas-api/2010JanMar/0158.html
20:40:11 [richardschwerdtfe]
      - Authors MUST render visible focus of the ADOM subtree element in
      the canvas area
20:40:51 [richardschwerdtfe]
      - Authors MUST render visible focus of the canvas subtree element in
      the canvas area
20:41:22 [richardschwerdtfe]
      - Authors MUST render visible focus of the canvas subtree element on
      the rendered canvas
20:42:31 [richardschwerdtfe]
      Authors MUST render the keyboard caret insertion cursor of the canvas
      subtree element on the rendered canvas
20:42:40 [cyns]
      authored content SHOULD respond to system settings for font, color
      and zoom.
20:43:47 [cyns]
      Authors SHOULD should ensure that the rendered canvas responds to
      system settings for font, color and zoom
20:44:14 [cyns]
      Authors SHOULD should ensure that the rendered canvas responds to
      system settings for font, color and zoom
20:44:17 [cyns]
      Authors SHOULD should ensure that the rendered canvas responds to
      system settings for font, color and zoom
20:44:25 [richardschwerdtfe]
      - Authors SHOULD ensure that the canvas rendering reflects the system
      font, color, and zoom settings
20:45:16 [richardschwerdtfe]
      Authors SHOULD ensure that the canvas rendering reflects the user
      settings for font, color, and zoom
20:46:06 [richardschwerdtfe]
      Define user settings as system, user agent, or web application
      settings
20:48:43 [silvia]
      silvia has joined #html-a11y
20:50:42 [jcraig]
      User settings is defined as text and zoom properties, rendered by a
      user agent, as affected by user and/or system settings. (e.g. If a
      user's settings affect standard DOM text rendered in the browser,
      authors should detect that difference and update the canvas to
      reflect the user's preference.)
