mHasScheduleFlush is meant to track mViewManagerFlushIsPending except mViewManagerFlushIsPending gets set to false just before we call ProcessPendingUpdates, whereas mHasScheduleFlush is set to false just after we call ProcessPendingUpdates.
There are a couple places where mViewManagerFlushIsPending gets set to false that don't clear mHasScheduleFlush though. This leaves mHasScheduleFlush true until we get another paint that changed something. This causes this code

in nsDisplayList::PaintRoot to always notify of invalidation (with webrender). This in turn causes a loop in the reftest harness: notify invalidation -> mozafterpaint -> update canvas -> paint -> notify invalidation.
This code changed a bunch until settling on the current design in bug 1404091.

In particular, not let ResizeReflow take the old and new size. Most of the
callers pass dummy values anyway.
Instead, use the old size of the layout viewport. This ensures we fire resize
events only if the layout viewport actually changes.
This is important because the first resize of the mobile viewport manager
after a navigation has an "old size" of 0x0, even though the layout viewport
is initialized on presshell initialization to the right size.
Thus, we fire resize events unnecessarily in that case, which is the root cause
for bug 1528052.
To do this, we need to shuffle a bit of code in nsDocumentViewer that deals with
delayed resizes, to set the visible area _and_ invalidate layout, rather than
setting the visible area and _then_ relying on doing a resize reflow.
Further cleanup is possible, though not required for my android resizing fix, so
will do separately.

When preceding mouse event is handled, that may cause changing style of the
target. Therefore, when an eMouseDown or eMouseUp event is handled, handlers
require the latest layout. Currently, nsViewManager::DispatchEvent() tries
to guarantee that with calling nsIPresShell::FlushPendingNotifications()
with FlushType::Layout. However, this just flushes the pending layout in
the PresShell associated with the nsViewManager instance. I.e., if the
target is in a child PresShell, its layout hasn't been flushed.
This patch makes PresShell::EventHandler::HandleEvent() flush pending
notifications at first of handling events using coordinates (only when
eMouseDown or eMouseUp, though). Then, when it realizes that the event
should be handled in a child PresShell, makes it flush its pending
notifications and then, recompute event target with the latest layout if
the layout is actually changed.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
Categories are useful to indicate: This much % of time was spent in this category.
The EVENTS category isn't a very good match for this. This category is currently
only set on labels of functions that handle the processing of an event. But
those functions are usually closer to the base of the stack, and the actual CPU
work during the processing of an event is usually in another category closer to
the top of the stack, e.g. in JS if we're running an event handler, or in LAYOUT
if we're hit testing the position of the event.
This changeset removes the EVENTS category and replaces all uses of it with the
OTHER category.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

This patch is not strictly relevant to the current bug, but doing the
work here nicely illustrates how the constructor we added in part 1 can
be used in existing parts of the codebase.
This patch removes its return value, because none of the call sites check it
except for one non-vital assertion.

This patch makes GetBounds(), GetScreenBounds() and GetClientBounds() more
obviously infallible, like existing functions such as GetNaturalBounds() and
GetClientSize(). This results in clearer behaviour in nsCocoaWindow.mm if
Objective C exceptions occur. Along the way, the patch removes some useless
failure checks for these functions.
The patch also removes the NS_IMETHOD from GetRestoredBounds and makes that
function MOZ_MUST_USE.
