+ * - Hold. prevents a batch from completing the pending task until

+ *
+ * The tasks associated with a batch are specified in a list at batch
+ * construction time as either task objects or plain functions.
+ * Batches are task objects, themselves, so they can be nested.

+/* exported SystemBackground */
+
+// READ THIS FIRST
+// Background handling is a maze of objects, both objects in this file, and
+// also objects inside Mutter. They all have a role.
+//
+// BackgroundManager
+// The only object that other parts of GNOME Shell deal with; a
+// BackgroundManager creates background actors and adds them to
+// the specified container. When the background is changed by the
+// user it will fade out the old actor and fade in the new actor.
+// (This is separate from the fading for an animated background,
+// since using two actors is quite inefficient.)
+//
+// MetaBackgroundImage
+// An object represented an image file that will be used for drawing
+// the background. MetaBackgroundImage objects asynchronously load,
+// so they are first created in an unloaded state, then later emit
+// a ::loaded signal when the Cogl object becomes available.
+//
+// MetaBackgroundImageCache
+// A cache from filename to MetaBackgroundImage.
+//
+// BackgroundSource
+// An object that is created for each GSettings schema (separate
+// settings schemas are used for the lock screen and main background),
+// and holds a reference to shared Background objects.
+//
+// MetaBackground
+// Holds the specification of a background - a background color
+// or gradient and one or two images blended together.
+//
+// Background
+// JS delegate object that Connects a MetaBackground to the GSettings
+// schema for the background.
+//
+// Animation
+// A helper object that handles loading a XML-based animation; it is a
+// wrapper for GnomeDesktop.BGSlideShow
+//
+// MetaBackgroundActor
+// An actor that draws the background for a single monitor
+//
+// BackgroundCache
+// A cache of Settings schema => BackgroundSource and of a single Animation.
+// Also used to share file monitors.
+//
+// A static image, background color or gradient is relatively straightforward. The
+// calling code creates a separate BackgroundManager for each monitor. Since they
+// are created for the same GSettings schema, they will use the same BackgroundSource
+// object, which provides a single Background and correspondingly a single
+// MetaBackground object.
+//
+// BackgroundManager BackgroundManager
+// | \ / |
+// | BackgroundSource | looked up in BackgroundCache
+// | | |
+// | Background |
+// | | |
+// MetaBackgroundActor | MetaBackgroundActor
+// \ | /
+// `------- MetaBackground ------'
+// |
+// MetaBackgroundImage looked up in MetaBackgroundImageCache
+//
+// The animated case is tricker because the animation XML file can specify different
+// files for different monitor resolutions and aspect ratios. For this reason,
+// the BackgroundSource provides different Background share a single Animation object,
+// which tracks the animation, but use different MetaBackground objects. In the
+// common case, the different MetaBackground objects will be created for the
+// same filename and look up the *same* MetaBackgroundImage object, so there is
+// little wasted memory:
+//
+// BackgroundManager BackgroundManager
+// | \ / |
+// | BackgroundSource | looked up in BackgroundCache

+// MetaBackgroundA|tor Me|aBackgroundActor
+// \ | | /
+// MetaBackground MetaBackground
+// \ /
+// MetaBackgroundImage looked up in MetaBackgroundImageCache
+// MetaBackgroundImage
+//
+// But the case of different filenames and different background images
+// is possible as well:

+// The notification will be expandable if either it has additional
+// elements that were added to it or if the @banner text did not

+// @banner text is added as the first element in the content section,
+// unless 'customContent' parameter with the value 'true' is specified
+// in @params.
+//
+// Additional notification content can be added with addActor() and
+// addBody() methods. The notification content is put inside a
+// scrollview, so if it gets too tall, the notification will scroll
+// rather than continue to grow. In addition to this main content
+// area, there is also a single-row action area, which is not
+// scrolled and can contain a single actor. The action area can
+// be set by calling setActionArea() method. There is also a
+// convenience method addButton() for adding a button to the action
+// area.
+//
+// If @params contains a 'customContent' parameter with the value %true,
+// then @banner will not be shown in the body of the notification when the
+// notification is expanded and calls to update() will not clear the content
+// unless 'clear' parameter with value %true is explicitly specified.
+//
+// By default, the icon shown is the same as the source's.
+// However, if @params contains a 'gicon' parameter, the passed in gicon
+// will be used.
+//
+// You can add a secondary icon to the banner with 'secondaryGIcon'. There
+// is no fallback for this icon.
+//
+// If @params contains 'bannerMarkup', with the value %true, a subset (<b>,
+// <i> and <u>) of the markup in [1] will be interpreted within @banner. If
+// the parameter is not present, then anything that looks like markup
+// in @banner will appear literally in the output.
+//
+// If @params contains a 'clear' parameter with the value %true, then
+// the content and the action area of the notification will be cleared.
+// The content area is also always cleared if 'customContent' is false
+// because it might contain the @banner that didn't fit in the banner mode.
+//
+// If @params contains 'soundName' or 'soundFile', the corresponding
+// event sound is played when the notification is shown (if the policy for
+// @source allows playing sounds).

+ *
+ * Then the recorded event log is replayed using handler functions

+ * foo_bar().
+ *
+ * Finally if the module has a function called finish(), that will
+ * be called.
+ *
+ * The event handler and finish functions are expected to fill in
+ * metrics to an object within the module called METRICS. Each
+ * property of this object represents an individual metric. The
+ * name of the property is the name of the metric, the value
+ * of the property is an object with the following properties:
+ *
+ * description: human readable description of the metric
+ * units: a string representing the units of the metric. It has
+ * the form '<unit> <unit> ... / <unit> / <unit> ...'. Certain
+ * unit values are recognized: s, ms, us, B, KiB, MiB. Other
+ * values can appear but are uninterpreted. Examples 's',
+ * '/ s', 'frames', 'frames / s', 'MiB / s / frame'
+ * value: computed value of the metric
+ *
+ * The resulting metrics will be written to @outputFile as JSON, or,
+ * if @outputFile is not provided, logged.
+ *
+ * After running the script and collecting statistics from the
+ * event log, GNOME Shell will exit.

+
+// USAGE:
+//
+// To correctly implement the gesture, there must be handlers for the following
+// signals:
+//
+// begin(tracker, monitor)
+// The handler should check whether a deceleration animation is currently
+// running. If it is, it should stop the animation (without resetting
+// progress). Then it should call:
+// tracker.confirmSwipe(distance, snapPoints, currentProgress, cancelProgress)
+// If it's not called, the swipe would be ignored.
+// The parameters are:
+// * distance: the page size;
+// * snapPoints: an (sorted with ascending order) array of snap points;
+// * currentProgress: the current progress;
+// * cancelprogress: a non-transient value that would be used if the gesture
+// is cancelled.
+// If no animation was running, currentProgress and cancelProgress should be
+// same. The handler may set 'orientation' property here.
+//
+// update(tracker, progress)
+// The handler should set the progress to the given value.
+//
+// end(tracker, duration, endProgress)
+// The handler should animate the progress to endProgress. If endProgress is
+// 0, it should do nothing after the animation, otherwise it should change the
+// state, e.g. change the current page or switch workspace.
+// NOTE: duration can be 0 in some cases, in this case it should finish
+// instantly.

+// Window Thumbnail Layout Algorithm
+// =================================
+//
+// General overview
+// ----------------
+//
+// The window thumbnail layout algorithm calculates some optimal layout
+// by computing layouts with some number of rows, calculating how good
+// each layout is, and stopping iterating when it finds one that is worse
+// than the previous layout. A layout consists of which windows are in
+// which rows, row sizes and other general state tracking that would make
+// calculating window positions from this information fairly easy.
+//
+// After a layout is computed that's considered the best layout, we
+// compute the layout scale to fit it in the area, and then compute
+// slots (sizes and positions) for each thumbnail.
+//
+// Layout generation
+// -----------------
+//
+// Layout generation is naive and simple: we simply add windows to a row
+// until we've added too many windows to a row, and then make a new row,
+// until we have our required N rows. The potential issue with this strategy
+// is that we may have too many windows at the bottom in some pathological
+// cases, which tends to make the thumbnails have the shape of a pile of
+// sand with a peak, with one window at the top.
+//
+// Scaling factors
+// ---------------
+//
+// Thumbnail position is mostly straightforward -- the main issue is
+// computing an optimal scale for each window that fits the constraints,
+// and doesn't make the thumbnail too small to see. There are two factors
+// involved in thumbnail scale to make sure that these two goals are met:
+// the window scale (calculated by _computeWindowScale) and the layout
+// scale (calculated by computeSizeAndScale).
+//
+// The calculation logic becomes slightly more complicated because row
+// and column spacing are not scaled, they're constant, so we can't
+// simply generate a bunch of window positions and then scale it. In
+// practice, it's not too bad -- we can simply try to fit the layout
+// in the input area minus whatever spacing we have, and then add
+// it back afterwards.
+//
+// The window scale is constant for the window's size regardless of the
+// input area or the layout scale or rows or anything else, and right
+// now just enlarges the window if it's too small. The fact that this
+// factor is stable makes it easy to calculate, so there's no sense
+// in not applying it in most calculations.
+//
+// The layout scale depends on the input area, the rows, etc, but is the
+// same for the entire layout, rather than being per-window. After
+// generating the rows of windows, we basically do some basic math to
+// fit the full, unscaled layout to the input area, as described above.
+//
+// With these two factors combined, the final scale of each thumbnail is
+// simply windowScale * layoutScale... almost.
+//
+// There's one additional constraint: the thumbnail scale must never be
+// larger than WINDOW_PREVIEW_MAXIMUM_SCALE, which means that the inequality:
+//
+// windowScale * layoutScale <= WINDOW_PREVIEW_MAXIMUM_SCALE
+//
+// must always be true. This is for each individual window -- while we
+// could adjust layoutScale to make the largest thumbnail smaller than
+// WINDOW_PREVIEW_MAXIMUM_SCALE, it would shrink windows which are already
+// under the inequality. To solve this, we simply cheat: we simply keep
+// each window's "cell" area to be the same, but we shrink the thumbnail
+// and center it horizontally, and align it to the bottom vertically.
