This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

Patch originally developed in bug 1406138, but landed in bug 1405790 since it
needs to land together with the upstream WR changes in PR 1816.

This keeps around mFinalDT but mostly doesn't use it (except for when creating
a PathBuilder). All playback is ripped out and we'll no longer hold references
to things to mFinalDT::GraidentStops or SourceSurfaces etc.
This helps keep us from accumulating all of the recorders.
The basic idea is to track weak references to the SourceSurfaces and Fonts that
we add UserData to in DrawEventRecorderPrivate and then clear these UserData's
when we're done recording.
This adds a RemoveAndDestroy helper to UserData to make this possible.
We need to grab UnscaledFont objects through WeakPtrs during metrics
calculations, but this only happens on Servo style worker threads
while the Servo font metrics mutex is locked (and while the main
thread is paused). So we use WeakPtrTraits to override the
thread safety assertion to allow OMT access through the WeakPtr
if the mutex is locked.
Since we can end up creating UnscaledFont objects from the style
worker threads too, we additionally need to allow the main thread
to access them through WeakPtrs.
It would be nice to avoid the dependency on layout/style/ here, but
I can't see a way to do that without putting the burden of the
annotation that the more permissive thread safety checks are allowed
on the WeakPtr<> declarations themselves.

(These are adding headers for types that are used in the modified files, to
provide those types' definitions.)
