With inert-top-controls turned on by default, we don't change the layout height
when the top controls are normally hidden. That is, if a user hides the URL bar
by scrolling, the page won't resize to use the newly available space. It'll lay
out as though the URL bar was still showing.

This patch makes an exception for cases where Chrome locks the URL bar in the
hidden state. e.g. Fullscreen or WebApp mode. In those cases, since the URL bar
can't be shown at all, there's no reason not to use the full height.

This CL prefixes the DidFinishLoading and DidReceiveData methods in
BrowserPluginDelegate, so they don't conflict with the
WebAssociatedURLLoaderClient versions which currently start with
lowercase letter. As part of the Blink rewrite to match Chromium style,
those will be colliding in MimeHandlerViewContainer.

Replace the GLSurface::Format enum with a proper class in preparation to
supporting types with configurable depth_size / samples / stencil_size.
Doing this in the current enum format would lead to a combinatorial
explosion.

The basic idea is that GetFormat can be used to initialize a new
surface with the same format as a pre-existing surface, and a
IsCompatible predicate is used to check if two formats are
equivalent for the purpose of avoiding BAD_MATCH errors. Code
should no longer be comparing formats to SURFACE_DEFAULT or similar.

Also add a new CreateOffscreenGLSurfaceWithFormat function that can
be used to request a specific surface format.

(These changes were suggested during review of https://crrev.com/2461803002 which is now forked into https://crrev.com/2586803003 .)

Web forms may not contain a username element, therefore it is not safe

Currently, all intents received by ChromeTabbedActivity are logged
as MobileReceivedExternalIntent despite there being many codepaths
within Chrome that also trigger intent dispatch.

A code search for Browser.EXTRA_CREATE_NEW_TAB shows a bunch of
callers that trigger intents and we logged them all as external.

This conflates whether we are receiving intents from other applications
or ourself.  The intent of this change (yuck, yuck, yuck) is to
split out intents that we dispatch ourselves and ones that an
actual external app did.

uses innovative string compression techniques to avoid bloat due to
i18n) to open the standalone content suggestions UI.

While the activity and menu item are not meant to be shipped in an

Past [1], 'ash/*' became a dependency tiedly coupled with
'is_chromeos'. This, for various reasons, helped to simplify the
dependency tree of mus+ash.

However, with the introduction of simple_wm [2], it should still be
possible to build and run Chrome/Ozone targeting LinuxOS
(not ChromeOS), with 'enable_package_mash_services' ON.

For that, this CL eases the gn checks for CHROMEOS specific header
inclusions in mash/package/mash_packaged_service.cc.

Reland of https://codereview.chromium.org/2614443002, which was reverted due to static initializer.

end_date is a replacement for expiry_date, which is deprecated by this change. The difference is that end_date is acts as a normal filter, and causes study to not be created when the date is past. expiry_date caused the study to be created, and forced to the default group.

This change introduces a generic default group name, which is used for the field trial API when a study doesn't specify one.

Since OSX Sierra, when we ask for the CGImage of a cursor image, it will return
a double-size CGImage with Retina display, which can't pass the sanity check.

=========================(deprecated)==================================
In this cl, we try to pass a half-size Rect hint to get CGImage with original
cursor size on both Retina and non-Retina display.
Also it fixs another issue that we render the cursor based on window coordinate
to a target in physical coordinate.
======================================================================

In this cl, we implemented a new common base class, CursorRenderer , to
merge the two implementations. Then we can handle the scaling and
rendering of cursor same on all platforms, also with other advantages:
caching scaled cursor image for better performance and only caring
about view coordinates (same handling to Retina and non-Retina).

The Ime test, testPastePopupShowAndHide, was flaking because of a race condition
where the paste popup menu was shown before the insertion handle was shown. This
is a problem because it allows the scenario:

1) Paste menu shown
2) Set composition
3) Insertion handle is shown

This causes the paste menu to not be hidden since setting the composition only
clears the menu by clearing the insertion handle. This CL makes setting the
composition wait for the insertion handle to be shown to guarantee this sequence:

1) Paste menu and insertion handle shown
2) Set composition
3) Insertion handle cleared
4) Paste menu hidden

This CL replaces append() with push_back() in Source/platform/.

There are too many references to change them all at once, so this CL is

Original issue's description:
> Add CHECKs to ResourceLoader to investigate crashes
>
> There are crash reports that |m_resource| is broken in
> ResourceLoader::didReceiveResponse. It is strange as ResourceLoader::m_resource
> is constant after its construction. To investigate the issue, this CL adds some
> CHECKs in ResourceLoader.

I also removed some ifdefs that are no longer necessary and some
windows code that isn't needed.

Using an interface makes the usage of MediaImage needlessly more
complicated than needed. A dictionary should keep the feature working
roughly the same way and improve developer's ergonomics.

Adds BeginFrameAck struct and updates the signature and callsites of
BeginFrameSource::DidFinishFrame(). This is split off from
https://codereview.chromium.org/2527283003/.

Observers will be required to use BeginFrameAcks to indicate the
result of a BeginFrame message. The acknowledgments will be used by the
DisplayScheduler to determine when all updates for a BeginFrame have
been received and trigger an early deadline.

A BeginFrame acknowledgment indicates:
1) completion of a specific BeginFrame by the observer,
2) whether or not the observer produced updates, and
3) the oldest frame that was incorporated into the last update from the
observer.

2) and 3) are in preparation for DevTool's BeginFrameControl, see
http://bit.ly/bfc-v1 and https://codereview.chromium.org/2411793008/.

Follow-up patches will add:
- correct calculation of |latest_confirmed_frame| in
  Scheduler/DisplayScheduler.
- missing DidFinishFrame() calls in observers
- integration of acks into CompositorFrame submission (to allow ack
  propagation from services / renderer compositor)
- modification of DisplayScheduler to rely on BeginFrameAcks.

The DCHECK could be triggered if sampling of results by SharedSampler on
background thread took longer than refresh cycle (1 second) and at the
same time user added or removed one of TaskManager columns handled by
SharedSampler.

This DCHECK was an errorneous assumption. I removed it and added a comment
explaining this situation.
