Currently items are painted with a context that has a transform of
-mLayerBounds.TopLeft(). This means that if TopLeft() changes the commands
will be in the wrong place because the -TopLeft() offset is baked into the
recording.
I don't think we've ever needed to support painting without this transformed
baked in so there were some infrastructure changes that needed to be made to
make this possible. Most of the problems come from the use of
gfxContext::GetClipExtents which expose the bounds of the underlying surface.
The biggest of these was fixed by the CreateClippedDrawTarget rewrite. The rest
should be handled by ensuring that the DrawTarget has bounds that are at least
as big as the union of the individual item bounds. i.e. GetClipExtents should
never intersect with bounds of the item.
This change has a couple of parts:
1. Store mLayerBounds.TopLeft() in the recording so that it will be subtracted
during replay
2. Use mLayerBounds as the Rect of the RecordingDrawTarget
3. Don't include mLayerBounds.TopLeft() in the transform during recording.
4. Adjust the dirty rect by recordingOrigin before we use it as a clip so that
it stays in the right place.
5. In PaintContainerItem the bounds parameter of PushLayer is in device space
so we need to account for the shift in the location of device space in the
DrawTargetRecording.

I'll need to add a couple of extra fields to the cache records, and realized that the current format
looks really fragile; in theory, it'd break if a font name ever contained a comma or semicolon
(unlikely though that may be). So let's fix it to be a bit more robust before we add to it further.
Using control characters from the C0 range to delimit fields/records, instead of ASCII punctuation,
removes the (tiny) risk of conflict with characters that actually occur in a name, and using
distinct field and record separators means that we can better check that the records we're loading
from the cache actually match the expected format.
(Given that the startup cache gets re-created when the build ID is updated, a change in the format
between versions wasn't going to cause problems for users; their old cache just gets blown away

On startup some program binaries are loaded from disk into an
in-memory cache. When we call create_program() we check if the
required program is present in this cache, and if so we call
glProgramBinary(). This is done early on so that the driver can
perform any necessary work in the background.
There may however be binaries in the disk cache that have not yet been
loaded in to memory, in order not to slow down startup. This change
makes it so that we attempt to load missing binaries from disk during
link_program(). The reason we do not do this in create_program() is
because that would result in loading all shaders from disk during
startup, which we want to avoid. Loading these shaders may therefore
take slightly longer than if they'd been loaded at startup, but will
still be much faster than recompiling them from scratch, and startup
will remain quick.
If loading the shaders on startup had previously timed out, then we do
not attempt to load shaders on demand as the disk is probably too slow
for that to be useful.

Webrender caches the program binaries of shaders used within the first
ten frames, so that on next startup it can load them from disk rather
than having to recompile them.
Previously it would load all binaries found in the disk cache on
startup, and when saving to the cache it would delete any existing
binaries that weren't used.
This changes it so that unused binaries are not deleted. The disk
space this requires is insignificant, but as the cache grows loading
all the shaders on startup can get expensive. To solve that we write a
whitelist of the shaders used during startup, and only load those
during the next startup.

Before this patch, we would use fallback for all border images. Now for
all but vector images we will use the WebRender border images
primitives. Vector images are an exception because the fallback is
clever in that it upscales the vector image and clips to only draw the
region it requires. This avoids artifacting but to do something similar
for WebRender as it is currently defined, we would increase our CPU and
memory footprint as we would need to produce the entire vector image
upscaled, not just the parts we need. In the future we should change
WebRender to accept different image resources for each of the segments.

The original patch in bug 1422530 checked whether we're currently hiding a given piece of text
because we're waiting for a resource to download, and used this as a signal that we should not
initiate another download.
However, that's not really a good criterion to use when we're doing font selection for a given
character, both because it's an indirect signal -- whether painting the text is suppressed will
depend on timing and the font-display property -- and because it doesn't consider whether any
resource that's already being downloaded will actually be relevant for the specific character
we're trying to display.
So this patch instead checks for a relevant in-progress load earlier in the font list during
the specific FindFontForChar call, so that when unicode-range is used to split a font across
multiple subsets, an in-progress load for one subset won't make us defer the downloads of other
subsets if they are also needed for the characters present in the text.
With this, the repeated blinking no longer happens on the site here, as loading of all the
required font subsets is initiated early.

Since JSWindowActors don't have direct access to synchronous messaging,
ChromeScript callers are going to need to migrate to asynchronous messaging
and queries instead.
Since there's no comparable API to sendQuery for frame message managers, this
patch adds a stub that uses synchronous messaging, but makes the API appear
asynchronous, and migrates callers to use it instead of direct synchronous
messaging. This will be replaced with a true synchronous API in the actor
migration.
Fortunately, most of the time, this actually leads to simpler code. The
`sendQuery` API doesn't have the odd return value semantics of
`sendSyncMessage`, and can usually just be used as a drop-in replacement. Many
of the `sendSyncMessage` callers don't actually use the result, and can just
be changed to `sendAsyncMessage`. And many of the existing async messaging
users can be changed to just use `sendQuery` rather than sending messages and
adding response listeners.
However, the APZ code is an exception. It relies on intricate properties of
the event loop, and doesn't have an easy way to slot in promise handlers, so I
migrated it to using sync messaging via process message managers instead.

The SpecialPowers set*Pref/get*Pref APIs currently use synchronous messaging
to set and get preference values from the parent process. Aside from directly
affecting callers of those APIs, it also affects callers of `pushPrefEnv`,
which is meant to be asynchronous, but is in practice usually synchronous due
to the synchronous messaging it uses.
This patch updates the getPref APIs to use the in-process preference service
(which most callers are expecting anyway), and also updates the callers of
the setPref and pushPrefEnv APIs to await the result if they're relying on it
taking effect immediately.
Unfortunately, there are some corner cases in tests that appear to only work
because of the quirks of the current sync messaging approach. The synchronous
setPref APIs, for instance, trigger preference changes in the parent
instantly, but don't update the values in the child until we've returned to
the event loop and had a chance to process the notifications from the parent.
The differnce in timing leads some tests to fail in strange ways, which this
patch works around by just adding timeouts.
There should be follow-ups for test owners to fix the flakiness.

This exposes the layers id on the APZ hit result testing API, and
updates callers to check the layers id is correct. This is mostly
unnecessary for these tests, but introduces machinery that will be
useful in Fission-enabled tests, where iframes may be OOP and have
different layers ids.

Also converts webgl.pref-16bpp from a VarCache pref to a normal pref, because
it doesn't need to be a VarCache pref.

This also removes the following prefs, because they're unused:
- media.autoplay.allow-muted pref
- media.autoplay.blackList-override-default

This is a temporary fix for the tests in test_pref_rollout_workaround. The
tests are permafailing because they are now always running with MOZ_WEBRENDER=0
which breaks assumptions inside the test.
gfxVRPuppet will be replaced with a fully asynchronous puppet automation that runs in the VR process.

Dragging the viewport scrollbar is accomplished by passing in a window
rather than an element.
Note that we can't just pass in the window's document.documentElement,
because coordinatesRelativeToScreen() would not give the correct result
for it. This is turn is because for a scrollable <div>, getBoundingClientRect()
returns the scroll frame's outer rect, but for the <html> element,
getBoundingClientRect() returns the root scroll frame's inner rect.

These changes are needed for consistently green runs with the new emulator with
"-gpu on".
Most changes are simple removal of fuzzy-if(geckoview) but I also needed to add
at least one new fuzzy-if.
In this configuration we can run reftests in just 2 chunks (20 minutes each on
opt/30 minutes on debug).

For some reason this causes some sort of failure in the doc upload
process. No other mach_commands.py files do this so this patch moves
the import into the functions that use it, which bypasses the problem.

In the future we're going to want VideoBridge connections from the RDD process into both the parent process and the GPU process.
This does the preparation work for unifying the way we create VideoBridges (using Endpoints, required for cross-process connections),
and detects which one to use based on where the video will be composited.
