Commit dd2cd6286c restricted callers of the screenshot methods to
portal implementations, gnome-settings-daemon and gnome-screenshot.
That restriction does make sense for the actual screenshot methods,
but `PickColor` is actually used by GTK in its color picker (and
therefore may be called from arbitrary applications).
Fix this by unrestricting access to `PickColor` again. Considering that
the method is always interactive, it's not very privacy/security-sensitive
anyway.

Add a "screenshot-taken" signal from the screenshot service's internal C
implementation, and use that to trigger the camera flash visual effect
and the click sound, allowing them to run in parallel with the PNG
compression instead of waiting until the file is complete to start.
This significantly improves perceived latency on high res setups such as
4K, 5K, or dual 4K screens.

On my local jhbuild setup some local stuff is not set up and
there's no pictures folder. This fixes a regression where it
blew up instead of saving to the home dir in this situation.

We currently only remove the screenshot operation from the shooter
map if the color pick operation completed successfully, but not if
it was cancelled. As a result, we now reject any further requests
from the same sender because we assume that there is an ongoing
operation.
Fix this by moving the cleanup to a finally clause that runs for
both code paths.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1288
Right now _createScreenshot() returns a tuple that indicates failure
when a sender requests a screenshot operation before a previously
started operation finished.
However that doesn't work for the PickColor() method, as it uses a
different return type than the other methods.
Address this by returning an error instead, which works in any case;
arguably trying to start multiple operations in parallel is an error
by the caller more than it is a failed operation anyway.

With color picking implemented in the compositor, we
can do better than letting the user pick a pixel with
the crosshair cursor, and present them with a preview
of the color that will be selected.
Do this by replacing the cursor with a custom icon and
apply a recoloring effect, where we replace a given color
with the color of the currently hovered pixel (similar
to a green screen).

Promises make asynchronous operations easier to manage, in particular
when used through the async/await syntax that allows for asynchronous
code to closely resemble synchronous one.
gjs has included a Gio._promisify() helper for a while now, which
monkey-patches methods that follow GIO's async pattern to return a
Promise when called without a callback argument.
Use that to get rid of all those GAsyncReadyCallbacks!
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1126
Commit da537cda43 moved the Shell.Screenshot API to GIO's async pattern,
but we never set the GError passed to the *_finish() functions and only
indicate failure by returning FALSE.
The expected behavior is to throw an error in that situation, so make sure
we do that.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1123
String.prototype.substr() doesn't support a negative length value
(to subtract from the full length), so we end up with a filename
of '' when hitting that code paths (a relative filename with '.png'
suffix).
Fix this by switching to String.prototype.replace() instead.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2091
The screenshot code has a fair bit of nested callbacks, which means
that it is a good use case for async functions and Promises.
Most code uses GIO's async pattern, which means it can be easily turned
into promises with Gio._promisify(); first handle the couple of cases
that need custom code though, starting with SelectArea.

Since ES5, trailing commas in arrays and object literals are valid.
We generally haven't used them so far, but they are actually a good
idea, as they make additions and removals in diffs much cleaner.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.

Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.

The legacy indent rule currently ignores arrow functions in parameters
to allow callbacks to not align with the other arguments:
this._someFunctionWithFairlyLongishName(arg1, arg2, arg3,
() => {
this._someOtherFunctionWithLongName(arg1);
});
But as ignoring entire nodes means we can end up with arbitrary
indentation, we should drop the exception. While this would make
the above "illegal" under the legacy config, it conforms with the
non-legacy style, so everything should be fine ...
... except that eslint starts to complain about some function args
that should be fine under the legacy config. Maybe it's thrown off
by the function-arg-in-arrow-function-in-function-arg structure, but
rather than figuring it out, let's just move those to the new style.

When selecting an area for screenshot we monitor the events while we've valid
coordinates in order to redraw the rubber band.
However, we don't stop ignore the motion events after button release and so
while animating. This might cause an unwanted effect if moving the mouse away
during fade out that is way more visible slowing-down the animations.
To fix this ignore any motion event once we've set the results.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/711
We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:
- they run entirely in C, while Tweener requires context switches
to JS each frame
- they are more reliable, as Tweener only detects when an animation
is overwritten with another Tween, while Clutter considers any
property change
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.
In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.

While we aren't using those destructured variables, they are still useful
to document the meaning of those elements. We don't want eslint to keep
warning about them though, so mark them accordingly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
Those unused arguments aren't bugs - unbeknownst to eslint, they all
correspond to valid signal parameters - but they don't contribute
anything to clarity, so just remove them anyway.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.
Spotted by eslint.

Selecting a screen area for a screenshot isn't the same as selecting
items in an icon view, so there's no strong rationale for picking
up the style from GTK. We stopped doing that for other elements like
tile previews long ago, so just use our own style here too.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/481
ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/361
A custom callback type is more convenient, but only as long as no
other callback type is required. We are about to add functionality
that does not return the filename to a screenshot saved on disk, so
prepare for that by moving to GIO's generic async callback pattern.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/286
Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.
https://bugzilla.gnome.org/show_bug.cgi?id=785084
We currently allow infinite number of screenshot requests to be active at
the same time, which can "dos" the system and cause OOM.
So fail subsequent requests for the same sender when a screenshot operation
is already running.
https://bugzilla.gnome.org/show_bug.cgi?id=737456
Taking an area screenshot doesn't work currently when in "grab mode",
for instance when the message tray or top bar menus are open. Fix
this by using GrabHelper for selecting the area, so grabs are properly
stacked for us.
https://bugzilla.gnome.org/show_bug.cgi?id=709126
We currently only ensure that width and height are positive, so it
is still possible to pass in values that don't make any sense at all
(which may even result in a crash when exceeding limits imposed by
X11).
There is nothing to screenshot outside the actual screen area, so
restrict the parameters to that.
https://bugzilla.gnome.org/show_bug.cgi?id=699752
The "flash" effect looks awkward when it fades in and out. Real
camera have an immediate flash of light, which then seems to fade
out as our eyes readjust the rapid change in lighting.
https://bugzilla.gnome.org/show_bug.cgi?id=691875
Since we're breaking API already, take this as an occasion to use a
separate interface for all the screenshot-related methods. The interface
name is org.gnome.Shell.Screenshot.
Internally, move all the related code to screenshot.js.
