When browser.xhtml switches to an <html> root element, the frame structure
changed and caused performance regressions on talos for tart and tresize.
browser.xhtml doesn't need scrolling, so we can disable it and keep performance
on par with XUL <window>.

In most cases, we run an animation on an object by changing its
offset-distance/offset-rotate, but keep its offset-path the same.
Building and flattening the path is sometime expensive, especially for
large path, so caching it makes sense to us and have a significant
performance improvement. This is for the main thread motion path
animations.
Note: Even though we support compositor animations for motion path,
nsIFrame::GetTransformMatrix() is still called during the animations for
other usages, so we may still build the gfx::Path on the main thread
without this patch, so this improvement becomes necessary for most cases.

So, we don't create a stacking context for this case. Besides, we also

For regular elements, whenever -moz-appearance is used, the CSS background is
ignored. Root elements were behaving specially, and the background color also
needed to be adjusted.
For example, for Windows 7, we have the following CSS rule;
```
:root {
background-color: transparent;
-moz-appearance: -moz-win-borderless-glass;
}
```
This change makes the root element more consistent with other elements, so the
extra `background-color: transparent` declaration is no longer necessary.
This change does not let content documents opt out of forced opaqueness:
Root content documents still get an opaque background color from an existing
check further down in this method.

In common cases where the caret is in a position:static frame subtree,
the caret's position (relative to canvas frame's custom content
container) should not be changed during scrolling.
However, when the caret is in a position:fixed or "stuck"
position:sticky frame subtree, the caret's position will change during
scrolling. We need to disable APZ to avoid jumpy carets.

This is the main patch to fix bug 1526268.
It is wrong to use the cached rects relative to the root
frame (ViewportFrame) to detect whether AccessibleCaret's position is
changed or not, because it doesn't account the root scroll frame's
scroll offset.
The effect is that we always produce "PositionChangedResult::Changed"
when scrolling on position:static elements, but
"PositionChangedResult::NotChanged" on position:fixed elements.
This patch fixes this by using the rect relative to custom content
container, which is the actually rect to set caret's position, to check
whether the position is changed or not.
Note that even with this patch, the caret on "position:fixed" element is
still jumpy during scrolling due to APZ. Part 3 will fixed this.

The #text-overlay and #image child divs were "position: absolute" under
the main AccessibleCaret div. However, they don't necessary need to be
position:absolute to achieve the desired layout. We can make them normal
in-flow elements to simplify the frame structure. There should not be
any perceivable change to the user.
Also, AccessibleCaret's position can made more accurate by using float
CSS pixels when converting it from app unit.

Lots of these callbacks have a non-`void*` final parameter, which UBSAN
complains about. This commit changes them to have a `void*` parameter.
This requires undoing the machinery added in the first two commits of bug
1473631: `TypePrefChangeFunc` and `PREF_CHANGE_METHOD`. The resulting code is
simpler (which is good) and more boilerplate-y (which is bad) but avoids the
undefined behaviour (which is good).

On the compositor thread in GPU process (i.e. web-renderer), gfxPlatform() is
not initialized, so we don't have the DrawTarget information.
Fortunately, all we need is to calculate the motion point and direction
vector, so we don't have to care about which backend we use.
Therefore, make PathBuilder as a parameter, so we can just pass a valid
PathBuilder on the compositor thread. For main thread (i.e. content
process), using the original way is fine.

the specified window size, but for Anrdoid, it should be computed with the

Currently, `nsFrameSelection::CommonPageMove()` is called before every caller
calls `nsFrameSelection::ScrollSelectionIntoView()`. However, when an editing
host has focus, the scroll target may be outside of it. In such case, without
moving caret, user may want only to scroll the scrollable element.
Chrome behaves like so. Chrome also can scroll outside scrollable element
of focused editing host. However, it scrolls caret into view only when
caret is moved actually. Therefore, it makes sense to follow this behavior.
This patch makes `nsFrameSelection::CommonPageMove()` also call
`nsFrameSelection::ScrollSelectionIntoView()`. However, it newly takes
`SelectionIntoView` flag for making callers can choose the condition. I.e.,
`ScrollSelectionIntoView()` should be called always, or only when selection
is actually changed, or shouldn't be called.
