Unfortunately, `EventChainVisitor` does not grab the `nsPresContext` with
`RefPtr` by itself. Therefore, there is no guarantee of the lifetime without
checking the origin when its subclasses are instantiated. This patch changes
it and subclasses to `MOZ_STACK_CLASS` since only `EventDispatcher::Dispatch()`
creates them in the stack with given `nsPresContext`. Additionally, it's
already been marked as MOZ_CAN_RUN_SCRIPT_BOUNDARY`. Therefore, the
`nsPresContext` instance has already been guaranteed its lifetime by the
caller. For making this fact stronger, this patch marks their constructors
as `MOZ_CAN_RUN_SCRIPT`. Therefore, nobody can create those instances without
guaranteeing the lifetime of `nsPresContext` and `dom::Event`. Note that
it may look like that `mPresContext` of `EventChainPostVisitor` is not
guaranteed. However, `EventChainPreVisitor` which gives `nsPresContext` to it
is also a stack only class. So, it won't be deleted before
`EventChainPostVisitor` instance.

This patch changes remaining things under `layout/`. However, there are some
places which still need to use `nsIPresShell`. That will be fixed in a
follow up bug.

Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead. So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).
Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.

Right now we just block the image returned from nsIFrame::GetCursor, which is
the first loading cursor image.
I think we should do the same we do when the image fails to load, which is to
fall back to the next image instead.
This patch moves all the custom cursor code selection logic to
EventStateManager, and lets the frame return a CursorKind and whether custom
images are allowed.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

This patch makes do_QueryFrame() accept const frame pointer e.g.
"const nsIFrame*", and also helps eliminate a few const_cast in Part 3.
Note that the fast path of do_QueryFrame is const-correct, but the slow
path is not (due to nsIFrame::QueryFrame() returns void*).
For example:
```
const nsIFrame* f;
nsBlockFrame* a = do_QueryFrame(f); // fast path, compile error.
nsIAnonymousContentCreator* b = do_QueryFrame(f); // slow path, still compiles.
```

The contain:paint clipping would be redundant and hence unnecessary in this
scenario, because:
- Scroll frames already clip their descendant frames.
- contain:paint has other (non-clipping-related) effects that prevent
descendant frames from escaping the scrollframe ancestor.
So, no further clipping is required.
This is a behavior change - it works around an issue that makes us fail to
repaint mousewheel-scrolled content inside of any scrollframe that returns true
from ShouldApplyOverflowClipping().

Currently, GetSplittableType() is called only in
nsCSSFrameConstructor::CreateContinuingFrame(). The splittable concrete frames
should inherit from nsSplittableFrame, and must explicitly create continuing
frame in CreateContinuingFrame(). Thus, no need to maintain GetSplittableType().

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.

This is needed only for CSS Grid since in other cases we're
only using IntrinsicISizeOffsets in the inline-axis and
the percentage basis is always indefinite for *intrinsic
sizing*. When calculating the intrinsic size of grid items
in the grid container's block axis however, we do have
a definite size for the grid area in the inline-axis and it
should be used per:
https://drafts.csswg.org/css-grid/#algo-overview
"2. Next, the track sizing algorithm resolves the sizes of
the grid rows, using the grid column sizes calculated in
the previous step."
(Percentage padding/margin for grid items is always resolved
against the grid area's inline-size nowadays.)
It's good to save some copy constructor calls.

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.

It's good to save a copy constructor call.
Also, make nsBlockFrame::SplitFloat() return void because the only
caller (BlockReflowInput::FlowAndPlaceFloat()) doesn't check its return
value, and (more importantly) because it only ever returns NS_OK.

ContentEventHandler::ExpandToClusterBoundary() doesn't check the return value of nsTextFrame::PeekOffsetCharacter(). Therefore, it may set its result to reversed offset. (e.g., when aForward is true and offset is 6, the result may be 5. When aForward is false and offset is 5, the result may be 6.)
For avoiding that, ContentEventHandler::ExpandToClusterBoundary() should check the result and only when it returns nsIFrame::FOUND, it should compute the proper offset.
On the other hand, it's too bad for ContentEventHandler that nsTextFrame::PeekOffsetCharacter() to return nsIFrame::CONTINUE_UNSELECTABLE when the user-select style is "all" because IME doesn't expect such cases.
Therefore, this patch adds additional argument to nsIFrame::PeekOffsetCharacter(), aOptions which is a struct containing bool members. The reason why it's not a bit mask enum is, such struct doesn't cause simple mistake at checking the value and the code is shorter. When mIgnoreUserStyleAll of it is true, this patch makes nsTextFrame not return nsIFrame::CONTINUE_UNSELECTABLE.
