3866f0d581ceaa165710feeee9f37fe1b0d7067d 12-Feb-2013 Mathias Agopian <mathias@google.com> split Surface in two classes: SurfaceControl and Surface

SurfaceControl is the window manager side; it can
control the attributes of a surface but cannot push buffers
to it. Surface on the other hand is the application (producer)
side and is used to push buffers to the surface.

Ensures that both the internal display and HDMI are blanked
or unblanked in tandem.

The input system needs to know about the window that has
focus, even if it is on a secondary display. So now we
send it the list of all windows and indicate which display
they are on. We filter the list of windows as necessary
when delivering touch events.

To keep things simple, monitor input channels and input
filters are not supported except on the main display.
We also do not pass the display id to applications; it is
only used inside the input system for now.

Properly scale touch coordinates based on the viewport.
This will be needed to ensure that touch works on external
display as well as when the internal display is being used
to simulate a different resolution.

The window manager is no longer responsible for telling the
input system about the display viewport.

4ed8fe75e1dde1a2b9576f3862aecc5a572c56b5 31-Aug-2012 Jeff Brown <jeffbrown@google.com> More improvements to the display manager.

Added more complete support for logical displays with
support for mirroring, rotation and scaling.

Improved the overlay display adapter's touch interactions.

A big change here is that the display manager no longer relies
on a single-threaded model to maintain its synchronization
invariants. Unfortunately we had to change this so as to play
nice with the fact that the window manager wants to own
the surface flinger transaction around display and surface
manipulations. As a result, the display manager has to be able
to update displays from the context of any thread.

It would be nice to make this process more cooperative.
There are already several components competing to perform
surface flinger transactions including the window manager,
display manager, electron beam, overlay display window,
and mouse pointer. They are not manipulating the same surfaces
but they can collide with one another when they make global
changes to the displays.

bd6e1500aedc5461e832f69e76341bff0e55fa2b 28-Aug-2012 Jeff Brown <jeffbrown@google.com> Add initial multi-display support.

Split the DisplayManager into two parts. One part is bound
to a Context and takes care of Display compatibility and
caching Display objects on behalf of the Context. The other
part is global and takes care of communicating with the
DisplayManagerService, handling callbacks, and caching
DisplayInfo objects on behalf of the process.

Implemented support for enumerating Displays and getting
callbacks when displays are added, removed or changed.

Elaborated the roles of DisplayManagerService, DisplayAdapter,
and DisplayDevice. We now support having multiple display
adapters registered, each of which can register multiple display
devices and configure them dynamically.

Added an OverlayDisplayAdapter which is used to simulate
secondary displays by means of overlay windows. Different
configurations of overlays can be selected using a new
setting in the Developer Settings panel. The overlays can
be repositioned and resized by the user for convenience.

At the moment, all displays are mirrors of display 0 and
no display transformations are applied. This will be improved
in future patches.

Refactored the way that the window manager creates its threads.
The OverlayDisplayAdapter needs to be able to use hardware
acceleration so it must share the same UI thread as the Keyguard
and window manager policy. We now handle this explicitly as
part of starting up the system server. This puts us in a
better position to consider how we might want to share (or not
share) Loopers among components.

Overlay displays are disabled when in safe mode or in only-core
mode to reduce the number of dependencies started in these modes.

64a55af0ac700baecb0877235eb42caac59a3560 26-Aug-2012 Jeff Brown <jeffbrown@google.com> Add plumbing for new surface flinger display API.

Cleaned up the implementation of Surface and SurfaceSession
to use more consistent naming and structure.

Added JNI for all of the new surface flinger display API calls.

Enforced the requirement that all Surfaces created by
the window manager be named.

Updated the display manager service to use the new methods.

848c2dc93b6795e171f3dd6f64ea0be65e2762ca 20-Aug-2012 Jeff Brown <jeffbrown@google.com> Stub out display manager service implementation.

Reverting to the previous stub as the display adapter registration
and the logical to physical mapping is not at all what we are going
to need moving forward.

Fixed up the service initialization order so that the display manager
service has a context from the start.

fa25bf5382467b1018bd9af7f1cb30a23d7d59f7 24-Jul-2012 Jeff Brown <jeffbrown@google.com> Add display manager skeleton.

The purpose of this change is to remove direct reliance on
SurfaceFlinger for describing the size and characteristics of
displays.

This patch also starts to make a distinction between logical displays
and physical display devices. Currently, the window manager owns
the concept of a logical display whereas the new display
manager owns the concept of a physical display device.
