// 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

// | Background Background |
// | | \ / | |
// | | Animation | | 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:
// ....

// to dismiss it. The actor is passed in through @params.actor.
//
// grab() can be called multiple times, with the scope of the grab being
// changed to a different actor every time. A nested grab does not have
// to have its grabbed actor inside the parent grab actors.
//
// Grabs can be automatically dropped if the user tries to dismiss it
// in one of two ways: the user clicking outside the currently grabbed
// actor, or the user typing the Escape key.
//
// If the user clicks outside the grabbed actors, and the clicked on
// actor is part of a previous grab in the stack, grabs will be popped
// until that grab is active. However, the click event will not be
// replayed to the actor.
//
// If the user types the Escape key, one grab from the grab stack will
// be popped.
//
// When a grab is popped by user interacting as described above, if you
// pass a callback as @params.onUngrab, it will be called with %true.
//
// If @params.focus is not null, we'll set the key focus directly

/*
* In order for transformation animations to look good, they need to be
* incremental and have some order to them (e.g., fade out hidden items,
* then shrink to close the void left over). Chaining animations in this way can
* be error-prone and wordy using just Tweener callbacks.
*
* The classes in this file help with this:
*
* - Task. encapsulates schedulable work to be run in a specific scope.
*
* - ConsecutiveBatch. runs a series of tasks in order and completes
* when the last in the series finishes.
*
* - ConcurrentBatch. runs a set of tasks at the same time and completes
* when the last to finish completes.
*
* - Hold. prevents a batch from completing the pending task until
* the hold is released.
*
* 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.
*
* These classes aren't specific to GDM, but were found to be unintuitive and so
* are not used elsewhere. These APIs may ultimately get dropped entirely and
* replaced by something else.

// 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.
//
// We don't compute some global order of windows right now for optimal
// travel when animating into the overview; windows are assumed to be
// in some stable order.
//
// 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_CLONE_MAXIMUM_SCALE, which means that the inequality:
//
// windowScale * layoutScale <= WINDOW_CLONE_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_CLONE_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.

* generator to automate a series of actions. These actions will
* trigger performance events and the script can also record its
* own performance events.
*
* Then the recorded event log is replayed using handler functions
* within the module. The handler for the event 'foo.bar' is called
* 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.

// Notification:
// @source: the notification's Source
// @title: the title

// @params: optional additional params
//
// Creates a notification. In the banner mode, the notification
// will show an icon, @title (in bold) and @banner, all on a single
// line (with @banner ellipsized if necessary).
//
// The notification will be expandable if either it has additional
// elements that were added to it or if the @banner text did not
// fit fully in the banner mode. When the notification is expanded,
// the @banner text from the top line is always removed. The complete
// @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).
