This updates more code that was using RelativeToParent() to use the
stacking context helper's ToRelativeWr* functions instead. This get us
closer to breaking the assumption that the WR stacking context order maps
1:1 to the layer tree structure.
MozReview-Commit-ID: HQrbvCgPOW4
This propagates the StackingContextHelper to the rest of the code that
builds WR display items, because we will need it in future patches to
stop using RelativeToParent.

This cleans up WebRenderRefLayer::RenderLayer to use typed coordinate
systems and the StackingContextHelper. Note that this patch contains a
functional change, because the clip rect pushed no longer includes the
transform on the ref layer itself. It's not clear to me why we were doing
that, and didn't seem correct.

This uses the StackingContextHelper and typed helper functions in
WebRenderLayer to simplify WebRenderTextLayer::RenderLayer. It also
removes the implicit assumption in WebRenderTextLayer that the parent
layer pushed a stacking context, which is an assumption we will
probably break in the future.

This is needed for the next patch, because the bullet frame WR rendering
code will need a StackingContextHelper to pass to the PushGlyphs call.
It also helps with some of the later patches in this series, when we get
rid of the RelativeToParent calls.

This is needed in part 3 to update WebRenderTextLayer::RenderLayer, so
that it no longer assumes the parent container layer has pushed a
stacking context, and instead explicitly uses the StackingContextHelper.

One of the things that I've noticed in profiling startup overhead is that,
even with the startup cache, we spend about 130ms just loading and decoding
scripts from the startup cache on my machine.
I think we should be able to do better than that by doing some of that work in
the background for scripts that we know we'll need during startup. With this
change, we seem to consistently save about 3-5% on non-e10s startup overhead
on talos. But there's a lot of room for tuning, and I think we get some
considerable improvement with a few ongoing tweeks.
Some notes about the approach:
- Setting up the off-thread compile is fairly expensive, since we need to
create a global object, and a lot of its built-in prototype objects for each
compile. So in order for there to be a performance improvement for OMT
compiles, the script has to be pretty large. Right now, the tipping point
seems to be about 20K.
There's currently no easy way to improve the per-compile setup overhead, but
we should be able to combine the off-thread compiles for multiple smaller
scripts into a single operation without any additional per-script overhead.
- The time we spend setting up scripts for OMT compile is almost entirely
CPU-bound. That means that we have a chunk of about 20-50ms where we can
safely schedule thread-safe IO work during early startup, so if we schedule
some of our current synchronous IO operations on background threads during the
script cache setup, we basically get them for free, and can probably increase
the number of scripts we compile in the background.
- I went with an uncompressed mmap of the raw XDR data for a storage format.
That currently occupies about 5MB of disk space. Gzipped, it's ~1.2MB, so
compressing it might save some startup disk IO, but keeping it uncompressed
simplifies a lot of the OMT and even main thread decoding process, but, more
importantly:
- We currently don't use the startup cache in content processes, for a variety
of reasons. However, with this approach, I think we can safely store the
cached script data from a content process before we load any untrusted code
into it, and then share mmapped startup cache data between all content
processes. That should speed up content process startup *a lot*, and very
likely save memory, too. And:
- If we're especially concerned about saving per-process memory, and we keep
the cache data mapped for the lifetime of the JS runtime, I think that with
some effort we can probably share the static string data from scripts between
content processes, without any copying. Right now, it looks like for the main
process, there's about 1.5MB of string-ish data in the XDR dumps. It's
probably less for content processes, but if we could save .5MB per process
this way, it might make it easier to increase the number of content processes
we allow.

Need to pass the default transform/opacity to compositor if animations

DeleteCompositorAnimations API to delete animations on the compositor,
especially calling this API before WebRenderLayerManager got destroyed.
