This should make the optimization landed earlier in this bug apply for
some of the NotifyThemeChanged() calls in nsWindow.cpp which are causing
all the extra invalidations.
If we know that system colors/fonts didn't change, we can avoid doing a
bunch of reflow work and the patch from earlier in the bug can avoid
re-rasterizing images too.

APZ can sometimes indicate that it will be consuming touch events, even though
the touch-action properties prohibit it. This can happen if, for example, APZ
is waiting on the main-thread for accurate touch-action information. In such
cases, the main thread has enough information to filter out these false positives.
This patch makes it do that, by plumbing the allowed touch behaviors into
the APZEventState code that triggers the pointercancel event.

We don't know why we see initialization failures in the telemetry which
makes it hard to investigate why users aren't getting WebRender and
instead fallback to basic. Let's expose the detailed error message
WebRender already generates and puts in the critical log.

The current notification enumerates all windows and calls
SysColorChanged on them.
The current implementation of SysColorChanged is not quite sound, as it
really needs most if not all of what ThemeChanged does: SVGs can use
system colors, so we need to also invalidate the image cache for
example.
It's also not clear it deals correctly with propagating system color
changes to other documents.
In some cases we were even firing both theme changes and system color
changes at the same time. Unify this code paths.

With current gecko, there are cases that compositor window is used even when it is not necessary. For example, fallback from DirectComposite with WebRender and fallback from double buffering with Compositor. With some gpu drivers, the fallbacks with compositor window causes rendering problem.

Note that the propagation of the target guid to places where the transform
will be applied is best-effort at the moment. In particular, the
InputAPZContext will result in the correct guid being available in places
that are called synchronously from the Recv*() functions, but not places
called asynhcronously (e.g. via DelayedFireSingleTapEvent).
To mitigate this, places where the transform is applied fall back on the
RCD-RSF if a guid is not available via InputAPZContext (added in a
subsequent patch).
The cases that this gets wrong are fairly edge casey (it requires (a) an
asynchronous codepath, (b) an event targeting a subframe, and (c) that
subframe having a "could not accept the APZ scroll position" transform),
so we just punt on them for now. If it turns out to be important to handle,
then options for doing so include (1) propagating the guid through each of
the affected asynchronous codepaths, or (2) attaching the guid to the event
itself.

nsBaseWidget::AllowWebRenderForThisWindow() limits WebRender usage to some type of windows. It was added by Bug 1377321, because initialization of WebRender was heavy weight in the past. It is not necessary anymore.

No functional change here, but this improves readability by using the
Rect and Size structs' operators, rather than breaking out the x/y/width/height
components and doing operations directly.

It doesn't make sense to mix mBounds with GetClientBounds(), as the windows
widget overrides both GetBounds() and GetClientBounds(). So if we're using
GetClientBounds() for the client bounds, we should be using GetBounds() for
the bounds.

These functions all have a single call site, and the call site clearly always
has rect in DesktopPixel units. So it makes sense to encode this in the API,
and propagate the strongly typed units.

gfx::Color is currently misused in many places. The DrawTargets expect
the color space to be in device space, e.g. what we are actually going
to draw using. Everything sitting above generally deals with sRGB, as
specified in CSS. Sometimes we missed the conversion from sRGB to device
space when issuing draw calls, and similarly sometimes we converted the
color to device space twice.
This patch splits the type in two. sRGBColor and DeviceColor now
represent sRGB and device color spaces respectively. DrawTarget only
accepts DeviceColor, and one can get a DeviceColor from an sRGBColor via
the ToDeviceColor helper API. The reftests now pass with color
management enabled for everything (e.g. CSS) instead of just tagged
raster images.
There will be a follow up patch to enable color management everywhere by
default on all supported platforms.
