In the upcoming patch to disable logging, we're going to conditionally
turn MOZ_LOG_TEST into a constant false. But for this instance of
MOZ_LOG_TEST in nsPresContext, turning it into a constant means that
|log| becomes unused. Since |log| isn't used after this point, let's
move the |gfxPlatform::GetLog| call into the MOZ_LOG_TEST call, removing
the temporary variable, and making the compiler happy.
I'm acting under the assumption that this is what's closest to what the
code does now, except without asserting in ~ErrorResult. It also seems
closest to what event listeners will do, both based on examining code
(EventListenerManager::HandleEventSubType, which I'm hoping is the right
code to look at, calls StealNSResult, and then stores it in a member
that's ignored by most callers) and based on testing (for both click
events, and for media query listeners with this patch, the exception
gets reported to the console as an unhandled exception). That said, I'm
not particularly well versed in the current error handling rules so I
may well be off here.
This code should presumably go away when we change this code to use
EventListeners in bug 1265622, so I don't think there's any spec that
covers this.
Without the patch, the mochitest hits the fatal assertion (after
reporting hitting the expected uncaught exception). With the
patch the test passes. (Tested locally.)

nsPresContext contains a mLastStyleUpdateForAllAnimations flag which is simply
used to prevent unnecessarily posting restyles when throttled animations are
already up to date. Since part 13 we now accurately record whether we have
posted a restyle for each throttled animation and only post a restyle if we
have not done so already. As a result, this flag is no longer needed since
calling PostRestyleForThrottledAnimations is effectively a noop when throttled
animations are up-to-date.
Since we want to track elements needing a restyle on EffectCompositor we need
to scope it to an nsPresContext rather than just making if a collection of
static methods.
The patch renames the existing functions (GetBounds(), GetClientBounds(), etc)
by adding an |Untyped| suffix. It then adds typed equivalents, and uses those
typed equivalents in all the call sites where it's easy to do so. The trickier
remaining call sites are converted to use the Untyped-suffix version.
Having to include all of Layers.h just to get at the definition of
LayerUserData is inconvenient, especially as most of the interesting
things in Layers.h can be forward-declared. Let's move LayerUserData to
its own header, so clients can include a small header for that,
forward-declare anything else they need from Layers.h, and reduce header
bloat.
The only substantive change here, apart from a few variables changing in
size from uint16_t to uint8_t, is FontFaceSet's use of SheetType::Unknown
(0xFF) instead of 0 for FontFaceRecords for script-created FontFaces.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
