This function (and helper functions that wrap it) will be used extensively
throughout layout code, so keeping it in APZCCallbackHelper seems awkward.
nsLayoutUtils would also be a reasonable place but has the downside that
adding a new function to it triggers recompiling the world.

We need it to live in BrowsingContext instead of WindowContext, because
we need to preserve the zoom level across same-origin navigation.
It'd be nice if it only lived in the top BC, but that's not possible at
the moment because a lot of tests rely on zooming only iframes. Some of
them can be adjusted for scaling the top instead, but not sure it's
worth it's worth fixing them and moving the zoom to be top-only, as it'd
be a bunch of effort, and the complexity and overhead of propagating the
zoom is not so big.
The print-preview-specific code in nsContentViewer is from before we did
the document cloning setup, and it seems useless. I've tested print
preview scaling before and after my patch and both behave the same.
The rest is just various test changes to use the SpecialPowers APIs or
BrowsingContext as needed instead of directly poking at the content
viewer.
I named the pres context hook RecomputeBrowsingContextDependentData, as
more stuff should move there like overrideDPPX and other media emulation
shenanigans.
I also have some ideas to simplify or even remove ZoomChild and such,
but that's followup work.

This code is used to determine the sizes of the top-level windows. However the
code doesn't cause quite desirable behavior (see the bug, and comment 15).
This patch does two things:
* Unifies the html / xul code-paths. This shouldn't change behavior (because
GetXULMinSize returns the fixed min-* property if present anyways), but
makes the patch a bit simpler.
* Makes the min-width of the XUL window be the pref size instead of the
min-size (for the cases where you have no explicit min-width). This looks a
bit counter intuitive, but it's the only way to guarantee that the content
will be shown. This matches the sizing algorithm that dialogs use by default
(via calling window.sizeToContent()), while allowing to undersize the window
via a fixed min-width property.
This in turn makes sizeToContent() work "by default" on XUL windows, avoiding
having to make JS listen to everything that possibly could change the layout of
the document (like resolution changes).

If we get a sub-pixel content size, rounding down may actually cause the content
to wrap, which is not desirable and would cause the content to be truncated.

This fixes the case where you have a focused input (or selection for <input
disabled>) in an <iframe> and move the focus outside of the iframe.

This rejiggers a bit the way selection focus is handled so that focusing a
disabled form control with the mouse handles selection properly, and hides the
document selection and so on.
This matches the behavior of other browsers as far as I can tell.
Given now readonly and disabled editors behave the same, we can simplify a bit
the surrounding editor code.

Since safe area insets uses on content, we need send it from chrome process to
content process.
SafeAreaInsetsChanged will be called per window position/size change (Next
patch is Android implementation for it), we have to calculate safe area insets
on widget/window per change.
Current implementation is that this value is top level document only like Blink
since https://github.com/w3c/csswg-drafts/issues/4670 isn't resolved yet.

This patch adds a menu item in "Toggle" -> "Paged Mode". If the item is
toggled, after finishing loading the document, the document will be
forced into paged mode.
The print settings in `nsLayoutDebuggingTools::SetPagedMode()` are
similar to `setupPrintMode()` in reftest-content.js.
Remove the hack in nsDocumentViewer::InitInternal() because we don't
want to set a new document when mIsPageMode = false.

The PreFullZoomChange event gives listeners an opportunity to capture
state before the viewport full zoom changes. Responsive Design Mode uses
this to save and later restore the resolution of the RDM pane.
