Previously we computed a caret frame each time we started display list building for a pres shell, and tracked a stack of these as we descended through subdocuments.
This meant that we couldn't know if the caret frame had changed before we started building, and we instead had to support invalidations in the middle of building.
Since there should only ever be one focused document, we can instead retrieve this from the focus manager, and find the sole caret frame for all documents we want to paint.

easy to add more buckets as needed (either to mArenaSizes, or more specific ones
like the style system has). But this is probably enough for now.

We clear mGlassDisplayItem before a full display list build. We use it so that we only mark the first glass item we encounter with the glass item flag.
For partial builds we use the bool mHasGlassItemDuringPartial to track the same thing, so we only mark one item as glass. Merging handles updating mGlassDisplayItem for partial builds.
So this means that we could have one item marked as a glass item in the old list and one item marked as a glass item in the new list.
If merging doesn't use the existing mGlassDisplayItem then it clears mGlassDisplayItem. If merging uses a new item that is a glass item it calls SetGlassDisplayItem on it, so it will only become the new glass item if there wasn't one there already.
So it is actually possible that both items with the glass flag make it into the final display list. Thus the number of display items in the display list with the glass flag can grow to any number, but it would have to be a very very weird state because the glass item is only allowed to be a themed background item coming from a doc element box frame (one per xul doc near the root).

This also changes behaviour a bit, previously we interleaved column and column group backgrounds. where we now put all the column group backgrounds behind all columns.
I believe this is the correct ordering as per CSS2.2 Appendix E.
Column backgrounds can overlap when using 'span', and we now render this in a different order, but this matches what other browsers do.

In bug 1527182 we made it so that APZ can directly drag-scroll scrollframes
that are inside SVG effects, because that's possible with WR on the compositor.
However the code changed in that bug was meant to be kept in sync with
a second piece of code. The second piece of code controls the generation
of ScrollInfo items for scrollframes inside SVG effects - since we can
APZ-scroll them with WR, we don't need the scrollinfo item anymore.
Producing the scrollinfo item was changing the structure of the APZ tree
in terms of where the transform ended up, and was causing badness with
untransforming the drag mouse events.
This patch adds a test that covers the scenario and also corrects the defect
by bringing the two bits of code back in sync.

This enables destructors for tagged unions in cbindgen, implemented in:
* https://github.com/eqrion/cbindgen/pull/333
Which allow us to properly generate a destructor for the cbindgen-generated
StyleBasicShape (which now contains an OwnedSlice).
For now, we still use the glue code to go from Box<BasicShape> to
UniquePtr<BasicShape>. But that will change in the future when we generate even
more stuff and remove all the glue.
I could add support for copy-constructor generation to cbindgen for tagged
enums, but I'm not sure if it'll end up being needed, and copy-constructing
unions in C++ is always very tricky.

The comment in nsDisplayTransform::GetTransformForRendering() clearly
says that |aOutOrigin| should return the same offset as GetTransform().
GetTransform() will pass the offset to GetResultingTransformMatrix()
which will round it in many cases to avoid subpixel blurry rendering.
But GetTransformForRendering() doesn't take this rounding into account,
thus contradicting the intent described by the comment.
This rounding is important to keep subpixel behavior consistent with
or without webrender enabled. Currently, SVG will be rendered blurry
in some cases if it's at a subpixel position. After fixing the problem
in non-webrender case, the strange blur still occurs in webrender case.
It turns out to be caused by this inconsistency.

ComputeRebuildRegion sets ForceDescendIntoIfVisible on all modified frames and their ancestors,
so we can use this to detect if a display list might have modified children by looking for this
flag on the container item.
We still need to run PreProcessDisplayList on the list, so that we can remove items that belong
to a deleted frame, and build the old items array (including placeholders for the deleted items)
so that it matches our DAG.
If we wanted to skip serialization to the old items array, then we'd need to remove the deleted
item entries from the DAG too, including connecting predecessors of the deleted entry to entries
that have that deleted entry as their predecessor. That's hard to do in-place, so we leave
the empty entries in the old items list to act as placeholders until we next merge this list
properly.

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.
