The math-depth implementation is refined to take into account the
ScriptPercentScaleDown and ScriptScriptPercentScaleDown constants (if the
parent's first valid font has a MATH table) in order to calculate the
scale factor between math-deth 0 and 1, and between 0 and 2 respectively.
Behavior is unchanged if the legacy scriptsizemultiplier attribute is
specified or if no MATH table is available.
The preference layout.css.math-depth.enabled remains disabled in nightly
until the remaining bit (support for font-size: math) is implemented in
bug 1667090.

This patch includes a couple of changes.
1) Notify contentful paint only during refresh driver ticks.
2) Not only the root document, sub document should also have their own
contentful paint entry.
3) Consider invisible text as contentful as well.

This happens after the test is finish when we unset the ui.useOverlayScrollbars pref which (I'm assuming because it must) causes reflow. When running a font-inflation related reftest we also unset the font inflation related prefs that were specified in the reftest.list file. This causes font-inflation to go from enabled to disabled and we detect that for the first time while reflowing the scroll frame.
Instead we should reflow when any pref that could affect font inflation is changed. I scanned the font-inflation code in PresShell and Document::GetViewportInfo for prefs are consulted, but I didn't go a super exhaustive search.

We were adding the unwriteable to the default margin. I was going to
consider not painting the headers / footers if they overlapped with the
content box of the page, but turns out our default configuration
overlaps slightly at the bottom, so I just punted on that.
Users can remove the headers / footers quite easily anyhow.

Android-components listens to the GeckoView callback onFirstContentfulPaint to
track whether a contentful paint has occured, in order to decide when to
thumbnail a tab. Currently this gets fired once per tab.
However, when the GeckoSession is paused, we clear cached resources in the
compositor. This means that when the session is resumed, the compositor does not
have the necessary information to render the page (such as painted content
buffers, or the webrender display list). Because android-components attempts to
capture a new thumbnail immediately upon resuming, it ends up capturing a blank
thumbnail.
To fix this, add a new callback onPaintStatusReset() which is invoked when the
cached resources are cleared. Android-components can listen for this to be
informed when the contentful paint is no longer visible. It can then wait until
the subsequent contentful paint occurs before capturing the thumbnail.

Content processes will now receive cached values for GetFontImpl() from the
parent process during initialization and whenever the theme changes.
This eliminates the use of several Win32k calls in content.

As a bonus, this also fixes a pre-existing bug that we never cleared the
mPrefChangePendingNeedsReflow flag after using it, so future pref changes
that shouldn't need a reflow would still trigger one.
