Previously, WebRender was getting a rectangle for reference frames
and stacking contexts, and it had to carefully treat the origin of this rectange:
- by offseting all the items in a stacking context
- by negatively compensating the sticky frame scroll port according to the
parent reference frame origin
With this change, we stop providing any non-zero origins. Instead we accomplish
the same behavior using existing API primitives, such as reference frames:
1. when a stacking context has an origin, we push another reference frame for it
2. when computing the sticky frame scroll port, we take this origin into account
This slightly simplifies Gecko-WR API, but more importantly it would allow WR to
get rid of this logic (of handling origins), which in turn would allow to switch
the reference frames from push()/pop() model to just define(), like we do for
scroll/sticky frames already.

This is a best effort attempt at ensuring that the adverse impact of
reformatting the entire tree over the comments would be minimal. I've used a
combination of strategies including disabling of formatting, some manual
formatting and some changes to formatting to work around some clang-format
limitations.

This lets us avoid having to put usize in the exported signatures from bindings.rs
It also avoids a heap allocation when defining a clip chain.

The overlap between debug flags and debug commands is a bit of a mess,
and this patch does not entirely clean it up. But this at least means
that the RenderBackend can react to pref changes in Firefox.

This commit attempts to lower the pain of modifying FrameMetrics.h.
It looks like most includes really only want ViewID or
ScrollableLayerGuid, so this commit factors them out into a separate
header. In the process FrameMetrics::ViewID is changed to
ScrollableLayerGuid::ViewID, which personally seems like a better
place for it now that we have RepaintRequest. Unfortunately that
requires a lot of places to be updated.
After this commit there are still a couple of major places that
FrameMetrics is included.
* nsDisplayList.h
* nsIScrollableFrame.h
* Layers.h
Those are going to be more tricky or impossible to fix so they're
not in this commit.

When taking multiple captures, have them get generated into separate
folders so that accidentally clobbering (or worse, partially clobbering)
a previous capture isn't a problem.
This part allows the caller to push a clip rect onto a stack that will
be used with any display items added to DisplayListBuilder. Said rect
will be intersected with the given clip rect for the display item (if
applicable).
The previous border-collapse beveling implementation assumed that there would
only be one beveled border per side in the whole table, which is... not true at all.
So a bunch of borders ended up clobbering other values in mBevelBorders and
never getting painted.
I'm actually somewhat scarily surprised that only this reftest seems to fail
without this patch...
Here we reuse most of the existing one-off beveling / border rendering support
in nsCSSRendering, and convert the Gecko bevels into a WebRender display list
using rects and borders. This is only remotely possible thanks to Gecko not
supporting dotted / dashed beveled borders :)
This would slightly easier and presumably also more efficient with a triangle
display item in WR instead of (ab)using the border display item to render the
bevel, but this is probably relatively edge-casey so maybe not worth it... In
any case I've left a TODO comment there, that can be a nice followup if we deem
it worth it.
Anyway, I'm _so_ sorry for the border trick, I was this (||) close to go and
rewrite our border collapsing code, but after a few tries I realized it'd take
me a whole lot of time (instead of the day that this has taken me).

The prefs, when enabled, will dump the gecko DL items followed by the
WR DL items that were generated from that gecko item. This allows us to
easily go from a DOM element with known id/class attributes to e.g. an
ImageKey of an image that was generated for that element.
Also, this logging can be enabled in CI builds just like gecko display-list
dumping, instead of the ifdef that we previously had in WebRenderLayerManager.
