3.2 Toggle audio, video, animated images, and animated/blinking text (P1)

1. Allow configuration not to render audio, video, or animated images in
the viewport or chrome except on explicit user request.
2. Allow configuration to render animated or blinking text in the viewport
or chrome as motionless, unblinking text.

Sufficient techniques

1. The user agent may satisfy this checkpoint by making video and animated
images invisible and audio silent, but this technique is not recommended.
2. The user agent may satisfy this checkpoint by showing still images in
place of video and image animations.
3. The user must still have access to all animated/blinking text content,
but the user agent may render it in a separate viewport (e.g., for large
amounts of streaming text).
4. The user agent may satisfy this checkpoint by always rendering animated
or blinking text as motionless, unblinking text.

Normative inclusions and exclusions

1. This checkpoint does not apply for content the user agent cannot
deterministically recognize as audio, video, animated images, or
animated/blinking text.
2. This configuration is required for content rendered without any user
interaction (including content rendered on load or as ther result of a
script) as well as content rendered as the result of user interaction that
is no an explicit user request (e.g., when the user activates a link).
3. This checkpoint must be satisfied for all implemented audio, video,
animated image, and animated/blinking text specifications; see the section
on conformance profiles.
4. When configured not to render audio, video, or animated images except on
explicit user request, the user agent is not required to retrieve them
until the user requests them explicitly.
5. Checkpoint 4.3 addresses user control of blinking effects caused by
rapid color changes.
6. Conformace profile labels: Visual text, Animation, Video, Audio

(merge bullets from existing 3.2, 3.3)


We should probably pull the inline definition out of the old 3.3 and put it
with the rest of the terms used in the document.

blinking text: text whose visual rendering alternates between visible and
invisible at any rate of change.
