* <p>This lists the maximum stall duration for each
* output format/size combination.</p>
* <p>A stall duration is how much extra time would get added
* to the normal minimum frame duration for a repeating request
* that has streams with non-zero stall.</p>
* <p>For example, consider JPEG captures which have the following
* characteristics:</p>
* <ul>
* <li>JPEG streams act like processed YUV streams in requests for which
* they are not included; in requests in which they are directly
* referenced, they act as JPEG streams. This is because supporting a
* JPEG stream requires the underlying YUV data to always be ready for
* use by a JPEG encoder, but the encoder will only be used (and impact
* frame duration) on requests that actually reference a JPEG stream.</li>
* <li>The JPEG processor can run concurrently to the rest of the camera
* pipeline, but cannot process more than 1 capture at a time.</li>
* </ul>
* <p>In other words, using a repeating YUV request would result
* in a steady frame rate (let's say it's 30 FPS). If a single
* JPEG request is submitted periodically, the frame rate will stay
* at 30 FPS (as long as we wait for the previous JPEG to return each
* time). If we try to submit a repeating YUV + JPEG request, then
* the frame rate will drop from 30 FPS.</p>
* <p>In general, submitting a new request with a non-0 stall time
* stream will <em>not</em> cause a frame rate drop unless there are still
* outstanding buffers for that stream from previous requests.</p>
* <p>Submitting a repeating request with streams (call this <code>S</code>)
* is the same as setting the minimum frame duration from
* the normal minimum frame duration corresponding to <code>S</code>, added with
* the maximum stall duration for <code>S</code>.</p>
* <p>If interleaving requests with and without a stall duration,
* a request will stall by the maximum of the remaining times
* for each can-stall stream with outstanding buffers.</p>
* <p>This means that a stalling request will not have an exposure start
* until the stall has completed.</p>
* <p>This should correspond to the stall duration when only that stream is
* active, with all processing (typically in android.*.mode) set to FAST
* or OFF. Setting any of the processing modes to HIGH_QUALITY
* effectively results in an indeterminate stall duration for all
* streams in a request (the regular stall calculation rules are
* ignored).</p>
* <p>The following formats may always have a stall duration:</p>
* <ul>
* <li>{@link android.graphics.ImageFormat#JPEG }</li>
* <li>{@link android.graphics.ImageFormat#RAW_SENSOR }</li>
* </ul>
* <p>The following formats will never have a stall duration:</p>
* <ul>
* <li>{@link android.graphics.ImageFormat#YUV_420_888 }</li>
* <li>{@link android.graphics.ImageFormat#RAW10 }</li>
* </ul>
* <p>All other formats may or may not have an allowed stall duration on
