Even with --enable-compile-warnings=error, avoid erroring out on deprecations
for the moment, since we are hitting many Clutter deprecations and some are
hard to fix.
If both spacing and -shell-grid-item-size are 0, as they would be with nothing
setting them, we enter an infinite loop where we try to compute the layout.
Avoid the situation entirely by defaulting -shell-grid-item-size to a sane
value instead of 0.

The "extension" object is what I previously called the "helper" object.
It contains the extension importer object as well as the metadata object.
Things that were previously added on to the metadata (state, path, dir, etc.)
are now part of this new "extension" object.
With the new importer changes brought on by the extension prefs tool,
extensions are left without a way to import submodules at the global scope,
which would make them rely on techniques like:
var MySubModule;
function init(meta) {
MySubModule = meta.importer.mySubModule;
}
That is, there's now a lot more meaningless boilerplate that nobody wants
to write and nobody wants to reivew.
Let's solve this with a few clever hacks.
Allow extensions to get their current extension object with:
let extension = imports.misc.extensionUtils.getCurrentExtension();
As such, extensions can now get their own extension object before the
'init' method is called, so they can import submodules or do other things
at the module scope:
const MySubModule = extension.imports.mySubModule;
const dataPath = GLib.build_filenamev([extension.path, 'awesome-data.json']);

Add two new APIs, "launchExtensionPrefs" to let SweetTooth let the user
launch the extension preferences tool directly from the browser. To allow
SweetTooth to check if an extension can be configured, add a new key to
the 'metadata', 'hasPrefs', which is returned by the GetExtensionInfo/
ListExtensions DBus methods.

A new tool, 'gnome-shell-extension-prefs' can load a new entry point from
extensions, 'prefs.js', which has an entry point to return a GTK+ widget.
This allows extensions to have their own preferences dialog, without each
extension needing to ship its own Python script and .desktop file.

ExtensionUtils is a new module that has a lot of miscellaneous things related
to loading extensions and the extension system put into a place that does not
depend on Shell or St.
Note that this will break extensions that have with multiple files by replacing
the old uuid-based importer with an object directly on the meta object.

If an extension fails to import, we will pass the error object
to logExtensionError, which fails to pass it onto DBus as an
error object is not a string. To fix, convert the error object
to a string before passing it to logExtensionError.

Clutter, since version 1.8, does The Right Thing™ inside the default
implementation of ClutterActor::map and ClutterActor::unmap, even for
non-container actors: it will iterate over the list of children and
map, or unmap, each one of them, respectively.
This means that the requirement to override map and unmap for composite
actors to map and unmap the internal children has been dropped.

Since our implementation of background-size is now CSS-compliant, we
do not need this subtexture hack that clips a "leak". The comment here
is also incorrect.
https://bugzilla.gnome.org/show_bug.cgi?id=633462
It seems that accidentally, two variables were swapped in one code path
of the background-size implementation, causing interesting but wrong
images for some elements.

Recent mutter changes made MetaShapedTexture not a ClutterTexture,
but instead a special ClutterActor subclass that implemented the texture-y
bits itself. Use recently introduced API in MetaShapedTexture so that we can
get the raw texture data and spit it out as a PNG.
Use the new meta_shaped_texture_get_image() to get a window's texture data.
meta_shaped_texture_get_image() flattens the image against any mask it may
have, so a screenshot of it should look exactly as it does on the display.

Instead of adding every rendered frame into the recording, drop frames
and only buffer and record enough frames to match the target framerate.
Increase the default frame rate from 15 to 30, since now that we're
actually enforcing framerate, it's noticeable that 15fps is not smooth.

The default pipeline was fairly aggressive about quality, and could
be too expensive for some computers. Decrease the quality setting for
the vp8 codec from 10 to 8, and increase the speed setting from 2 to 6.
(Basically, quality affects the visual fidelity of the end result, while
speed affects how much CPU the encoder uses to get a high compression
ratio at that quality level.)
Remove videorate from the pipeline, since the GStreamer VP8 encoder can
handle variable-framerate streams. This means that we won't spend CPU
encoding duplicate frames added by videorate.
