- gfxVRExternal Enables other processes to present
real or simulated VR hardware to Firefox.
- This functionality is disabled by default, under
dom.vr.external.enabled.
- VRDisplayInfo, VRControllerInfo, and associated
structs have been restructured to ensure internal
state is not exposed via shmem interface.
- Some refactoring to convert structs to
POD types, enabling them to be located
in shmem and be memcpy'd.
- Work needed before unpreffing marked
with "TODO" comments.

This code was originally added to debug the frame visibility code.
However it wasn't architected correctly and makes the compositor use an
untrusted layers id from content. Instead of fixing this I'd rather just
delete it, since it's a big pile of code that is basically a debugging
tool that nobody owns anymore.

image.animated.decode-on-demand.threshold-kb is the maximum size in kB
that the aggregate frames of an animation can use before it starts to
discard already displayed frames, and redecode them as necessary. The
lower it is set to, the less overall memory we will consume at the
expense of execution time for as long as the tab with the animation(s)
above the threshold are kept open.
image.animated.decode-on-demand.batch-size is the minimum number of
frames we want to have buffered ahead of an animation's currently
displayed frame. The decoding will request this number of frames at a
time to maximize use of memory caching. Note that this is related to the
above preference as well; increasing the batch size will in effect raise
what the minimum threshold. This simplifies the logic in patches later
in the series.
image.mem.volatile.min_threshold_kb is the minimum buffer allocation for
an image frame in KB before it will use volatile memory. If it is less
than it will use the heap. This only is set to > 0 on Android.
image.mem.animated.use_heap forces image frames to use the heap if it is
for an animated image. This is only enabled for Android, and was
previously a compile time option also for Android.
The image decoding thread pool can grow to be quite large, up to 32
threads, depending on the number of processors on the system. If the
user is not actively browsing, these threads are occupying resources
which could be reused elsewhere. After the timeout period, it will
release up to half of the threads in the pool.

This commit adds a paint worker thread pool to PaintThread, and dispatches
tiled paints to it. The thread pool is only created if tiling is enabled,
and its size is set by 'layers.omtp.paint-workers' and defaults to 1. If
-1 is specified, it will be sized to 'max((cpu_cores * 3) / 4, 1)'.
The one tricky part of dispatching tiled paints to a thread pool is the
AsyncEndLayerTransaction message that must execute once all paints are
finished. Previously, this runnable would be queued after all the paints
had been queued, ensuring it would be run after they had all completed.
With a thread pool, there is no guarantee. Instead this commit, uses
a flag on CompositorBridgeChild to signify whether all of the paints
have been queued ('mOutstandingAsyncEndLayerTransaction'), and after
every tiled paint it is examined to see if that paint was the last
paint, and if it is to run AsyncEndLayerTransaction. In addition,
if the async paints complete before we even mark the end of the
layer transaction, we queue it like normal.
The profiler markers are also complicated by using a thread pool.
I don't know of a great way to keep them working as they are per
thread, so for now I've removed them. I may have been the only
one using them anyway.

- Ensure ovr_GetSessionStatus is polled even when a VR presentation
is not active.
- When we fail to initialize an Oculus Session or detect VR hardware,
immediately unload the Oculus Library as we can't poll for ShouldQuit
without a valid Oculus session.
- When we poll ovr_GetSessionStatus, we are now updating the mounted state
in VRDisplayInfo::mIsMounted.
- Added prefs to control enumeration throttling and timeout to release
VR hardware when inactive.
- Some refactoring to make frame loop more understandable and less
brittle.
- When throttling enumeration, we ensure that all other VR apis
also throttle enumeration so that they don't pick up the same device
during throttling.
- Some long functions in VRManager have been broken up and
had their inner-workings documented in more detail.

This was previously limited to 2 per principal and 4 total on
mobile. Mobile GPU drivers have progressed a lot since the limit was
put in place, and the strict limit is causing webcompat issues on
google maps.
Increase to 8 per principal and 16 in total, bringing us
closer in line with Chrome. Make these limits contrallable via a pref
so that if there are any problems it is easy to change.

High resolution, high framerate was disabled by default on old AMD cards on the provisio that it was bad. But this assumes that the CPU decoder could do it better.
This assumption appears fragile at best, as CPU with those old adapter are likely to be old and underpower to start with.
Chrome doesn't appear to restrict use of those cards to a given resolution.
So we disable this restriction, while making it user configurable.

This commit removes the `layers.omtp.force-sync` preference and replaces
it with a preprocessor define that is commented out. This commit also
changes the behavior of force-sync so that it also does synchronization
with CompositorBridgeChild like normal OMTP. This simplifies the code
and makes using a preprocessor define easier.

Add a new TextureClientData type, AndroidNativeWindowTextureData,
backed by a SurfaceTexture in single-buffer mode. It uses the
NativeWindow API, which provides producer-side access to the buffer.
This provides a DrawTarget which can be used to paint directly in to
the SurfaceTexture, which can then be composited using a SurfaceTextureHost.
Due to API restrictions it is not possible to read from a NativeWindow
while the corresponding SurfaceTexture has ownership of the
buffer. TiledContentClient now handles that by painting the additional
region that it cannot copy from the front buffer, if required.

This patch adds a new tolerance pref, which controls how far the second touchdown
is allowed to be from the first touchdown when detecting a multi-tap gesture
such as double-tap or one-touch-pinch. This stops the one-touch-pinch code
from inadvertently triggering when the user does a tap followed by a second tap
far away from the first.
The default value for the new pref is 5x the touch-start tolerance pref. This
seems to provide a reasonable behaviour for me, although this value could
probably be tuned.

This commit adds the pref, 'apz.keyboard.passive-listeners', to allow web
content to have passive key event listeners and use keyboard APZ. When we are
allowing passive listeners, we need to dispatch the input to content and can
no longer consume the event. So we use mHandledByAPZ in nsXBLWindowKeyHandler
to determine whether we still need to do the default action, or whether it
has been done by APZ.

Ideally, we definitely want APZ in remote popup browsers for the sake of
responsiveness. However, there are currently some serious painting and
checkerboarding issues that make APZ popups unsuitable for release
populations.
Once these issues are addressed, we should enable the preference by default.
But given the relative lack of testing, and the issues we've seen so far, we
should keep the preference so that we can disable it with a hotfix if further
issues arise.
