/*
|

* The following prefs are used to control the behaviour of the APZC.
|
||||
* The default values are provided in gfxPrefs.h.
|
||||
*
|
||||
* "apz.allow-checkerboarding"
|
||||
* Pref that allows or disallows checkerboarding
|
||||
*
|
||||
* "apz.asyncscroll.throttle"
|
||||
* The time period in ms that throttles mozbrowserasyncscroll event.
|
||||
*
|
||||
* "apz.asyncscroll.timeout"
|
||||
* The timeout in ms for mAsyncScrollTimeoutTask delay task.
|
||||
*
|
||||
* "apz.axis_lock_mode"
|
||||
* The preferred axis locking style. See AxisLockMode for possible values.
|
||||
*
|
||||
* "apz.content_response_timeout"
|
||||
* Amount of time before we timeout response from content. For example, if
|
||||
* content is being unruly/slow and we don't get a response back within this
|
||||
* time, we will just pretend that content did not preventDefault any touch
|
||||
* events we dispatched to it.
|
||||
*
|
||||
* "apz.cross_slide_enabled"
|
||||
* Pref that enables integration with the Metro "cross-slide" gesture.
|
||||
*
|
||||
* "apz.enlarge_displayport_when_clipped"
|
||||
* Pref that enables enlarging of the displayport along one axis when the
|
||||
* generated displayport's size is beyond that of the scrollable rect on the
|
||||
* opposite axis.
|
||||
*
|
||||
* "apz.fling_friction"
|
||||
* Amount of friction applied during flings.
|
||||
*
|
||||
* "apz.fling_repaint_interval"
|
||||
* Maximum amount of time flinging before sending a viewport change. This will
|
||||
* asynchronously repaint the page.
|
||||
*
|
||||
* "apz.fling_stopped_threshold"
|
||||
* When flinging, if the velocity goes below this number, we just stop the
|
||||
* animation completely. This is to prevent asymptotically approaching 0
|
||||
* velocity and rerendering unnecessarily.
|
||||
*
|
||||
* "apz.max_velocity_inches_per_ms"
|
||||
* Maximum velocity in inches per millisecond. Velocity will be capped at this
|
||||
* value if a faster fling occurs. Negative values indicate unlimited velocity.
|
||||
*
|
||||
* "apz.max_velocity_queue_size"
|
||||
* Maximum size of velocity queue. The queue contains last N velocity records.
|
||||
* On touch end we calculate the average velocity in order to compensate
|
||||
* touch/mouse drivers misbehaviour.
|
||||
*
|
||||
* "apz.min_skate_speed"
|
||||
* Minimum amount of speed along an axis before we switch to "skate" multipliers
|
||||
* rather than using the "stationary" multipliers.
|
||||
*
|
||||
* "apz.num_paint_duration_samples"
|
||||
* Number of samples to store of how long it took to paint after the previous
|
||||
* requests.
|
||||
*
|
||||
* "apz.pan_repaint_interval"
|
||||
* Maximum amount of time while panning before sending a viewport change. This
|
||||
* will asynchronously repaint the page. It is also forced when panning stops.
|
||||
*
|
||||
* "apz.touch_start_tolerance"
|
||||
* Constant describing the tolerance in distance we use, multiplied by the
|
||||
* device DPI, before we start panning the screen. This is to prevent us from
|
||||
* accidentally processing taps as touch moves, and from very short/accidental
|
||||
* touches moving the screen.
|
||||
*
|
||||
* "apz.use_paint_duration"
|
||||
* Whether or not to use the estimated paint duration as a factor when projecting
|
||||
* the displayport in the direction of scrolling. If this value is set to false,
|
||||
* a constant 50ms paint time is used; the projection can be scaled as desired
|
||||
* using the apz.velocity_bias pref below.
|
||||
*
|
||||
* "apz.velocity_bias"
|
||||
* How much to adjust the displayport in the direction of scrolling. This value
|
||||
* is multiplied by the velocity and added to the displayport offset.
|
||||
*
|
||||
* "apz.x_skate_size_multiplier", "apz.y_skate_size_multiplier"
|
||||
* The multiplier we apply to the displayport size if it is skating (current
|
||||
* velocity is above apz.min_skate_speed). We prefer to increase the size of the
|
||||
* Y axis because it is more natural in the case that a user is reading a page
|
||||
* that scrolls up/down. Note that one, both or neither of these may be used
|
||||
* at any instant.
|
||||
* In general we want apz.[xy]_skate_size_multiplier to be smaller than the corresponding
|
||||
* stationary size multiplier because when panning fast we would like to paint
|
||||
* less and get faster, more predictable paint times. When panning slowly we
|
||||
* can afford to paint more even though it's slower.
|
||||
*
