Work will be split:
- Basic window
- Use WidgetDelegate to control behavior
- Finalize cosmetic decisions: type of window, bounds, and location

Add OverlaySurfaceEmbedder.

Used by PictureInPictureWindowController to embed a surface into
an OverlayWindow. By embedding a surface into the window, this
sets up the surface layers to show content.

Future work, such as adjusting gutter layers to handle various window
sizing, will come in future patches.

Add window controller for Picture in Picture.

This change adds an overall controller for the picture in picture
window. This class will control creation/destruction of the window,
as well as embedding the appropriate surface for showing media content
(future patch).

This controller is currently created per-WebContents, rather than per
Browser instance or Browser window. This behavior is still being
determined and will be updated. Tests will be added when this is more
fleshed out.

[Picture in Picture] Show video in OverlayWindow.

This change allows videos to be shown in picture in picture mode.
When the picture in picture media controls button on a video player
is clicked, a window opens and the corresponding video plays in the
window.

This works behind a flag. This is the first of more patches and lays
the ground work for additional behavioral implementations and tests.

[Picture in Picture] Determine initial window bounds.

Besides the initial window position and size, the user controls this
behavior. This change makes OverlayWindowViews a views::Widget, which
gives it more control over windowing behavior. Update sizing behavior
and determining window bounds, per UX guidelines.

This change also makes minor cosmetic changes (e.g. window type) to
temporarily make work in progress changes easier.

[cc::SurfaceLayer] Allow cc::SurfaceLayer to stretch content via ui::Layer.

ui::Layer has a cc::SurfaceLayer and can set its primary surface. This
change allows ui::Layer to also set whether or not cc::SurfaceLayer
should stretch its content to fill the surface bounds, which will either
stretch or shrink to fit the surface.

This change is driven by the intent for Picture-in-Picture to be able
to scale the video (contents) to fit into the PiP window bounds.
Since the PiP surface embedder, or OverlaySurfaceEmbedder, utilizes a
ui::Layer, this change would allow the ability to customize the
cc::SurfaceLayer be exposed. Further work for the PiP sizing will be
done, including maintaining the aspect ratio.

Picture-in-Picture has stopped when WMPI is deconstructed. The

effect is the PiP interstitial will be hidden.

If the client is not in Picture-in-Picture mode, this is a no-op.

[Picture in Picture] Add custom frame for window.

This change adds a custom views::NonClientFrameView for
OverlayWindowViews and modifies some of the views::Widget params.

The window continues to lack a title bar (min, max, close). It now
can be resized by dragging the edges of the window and dragged around
the display by dragging the contents of the window (not edges).

This changes does not take into account keeping aspect ratio or updating
the size of the embedded surface.

[Picture in Picture] Increase window border thickness.

Increasing the border thickness for a larger surface area to be able
to resize the window. This change is initiated from feedback to have
a larger drag-to-resize area.

This is currently an arbitrary value to gain feedback on the experience.

[Picture in Picture] Make window non-modal.

Modality currently makes Picture in Picture a feature you can enter but
can never leave.

This is an issue on ChromeOS, where the user is unable to interact with
other windows on the screen, which means there is no way to exit
Picture-in-Picture mode.

Modality is not intended for this feature.

[Picture in Picture] Resize cc::SurfaceLayer gracefully.

Currently, when the Picture-in-Picture window is resized, the video
(shown as the cc::SurfaceLayer) does not resize with it. This change
makes the cc::SurfaceLayer resize with the window.

Setting the new cc::SurfaceLayer size is required. |frame_size_in_dip_|,
which is set when the SetShowPrimarySurface() is initially called,
is used as the maximum size of cc::SurfaceLayer. This size needs to be
up to date for cases where the window is resized to be larger than the
initial size.

Sorry, this's probably the wrong place to post - but I didn't quite know if I should create a whole topic about this, but long story short:

I've been following the implementation of PIP... but it's not working on Netflix (I imagine that  it's because the peculiar and unique way that Netflix system works)...

But.. is there any plans to make PIP compatible with Netflix site?

How do you test that it's not working?
You may want to try the non-official Picture-in-Picture chrome extension as it works for me: https://github.com/beaufortfrancois/picture-in-picture-chrome-extension/issues/3

You can find current implementation status at https://github.com/WICG/picture-in-picture/blob/master/implementation-status.md

Primary window work has been completed. Future modifications will be tied to respective crbugs.
