The difference is that PostRestyleEventForCSSRuleChanges sets
mRestyleForCSSRuleChanges true. In a subsequent patch,
we propagate a new TraversalRestyleBehavior flag to servo side
if mRestyleForCSSRuleChanges is true.

We need to request an animation-only restyle to force flush all throttled
animations on main thread when we handle an event with coordinates
(e.g. mouse event).

This patch aims to speed up the lookup and storage of DisplayItemData objects, by removing a level of indirection and preventing the previously required hashtable lookup in order to access these. Instead it stores an array of pointers on each frame that allows direct access to the DisplayItemData object by dereferencing the frame. Since most frames get either 1 or 2 DisplayItemData objects attached to them a specialized class is used that is of minimal size (2 * sizeof(void)) and that performs well for sizes 1 or 2.

There are situations where events may be handled out-of-order. Allow
coalescing to happen backwards in time as well as forwards to cover them.

The call that's causing the crash seems to be [1], that is, we're trying to
recreate frames for the root element, which should always have a frame created
at the initialization of the PresShell.
So the function I removed in that bug had something like the following:
if (!mDidInitialize) {
// Nothing to do here. In fact, if we proceed and aContent is the
// root we will crash.
return NS_OK;
}
Which PostRecreateFramesFor doesn't guard against (because I thought it was not
needed, per tryserver results).
Sounds a lot like we do need that check, though I'd like to have a testcase
where it happens :(

Say there's a single lag event, a GC or a busy loop, during which the user
types several characters.
Is this one (lag) event? Several (input) events?
We have INPUT_EVENT_RESPONSE_MS which will accumulate several lagged events in
this case. However, that is more of an indication of how users use Firefox than
how good we've been at eliminating sources of lag.
INPUT_EVENT_RESPONSE_COALESCED_MS records the coalesced time spend waiting for
responses to input events. So in this case it will record one value for the
entire duration of the lag.

This also moves the NoteStyleSheetsChanged to RecordStylesheetChange, which
makes more sense, and stopped special-casing author styles, since it's not
needed now.

It's not only inefficient, but also prone to buggyness. Since styles may not be
up-to-date when it happens.
Post a reconstruct instead, which ensures a style flush happens before running
frame construction.

It is possible that events created before the OS goes to sleep will remain
unhandled until after the OS wakes. They will have long response times on
platforms where TimeStamp increments during sleep (like Windows) even though
they really shouldn't. (and the user likely doesn't care if they do).
So don't record those.

NotifyApproximateFrameVisibilityUpdate gets the displayport so we want the base rect set before calling it.
We also don't want to record the displayport if we ignored it in the actual visibility pass.
We want to use a similar model as Chrome on Android does for scaling our display of web content, that is use font inflation for desktop pages and plain text zooming for everything else.
Since we don't want to simply clobber any text zoom that might have been set by the user/front-end code, we allow setting and storing the system font scale separately on the PresContext. We then calculate the effective text zoom value as the product of the system font scale and the current text zoom value.
Any function that is using the PresContext's TextZoom value for layouting/rendering is switched over to this new EffectiveTextZoom value, whereas functions that are interested in the text zoom as actually set by the user/front-end (e.g. the nsDocumentViewer, or the code responsible for copying text and full zoom settings into the new PresContext on page navigation) continue using the plain TextZoom value.
As long as font inflation is enabled in principle (e.g. font.size.inflation.minTwips != 0), every page starts out as eligible for font inflation until the relevant meta viewport tags marking the page as "mobile friendly" have been detected. Since the PresShell caches the font inflation state and only recalculates it when necessary, we make use of that and set the PresContext's system font scale as necessary whenever the font inflation state has been refreshed.

Instead of copying and concatenating strings into an mDest buffer in
SamplerStackFramePrintfRAII, require callers to keep the string buffer alive
for the duration of the current scope, and store the pointer to the annotation
string in the ProfileEntry. During stackwalking, concatenate the label and the
annotation (separated by a space) and store the resulting string in the
profile buffer.
