This fixes PrintTargetWindows::BeginPrinting to detect when the
user cancels and have it return NS_ERROR_ABORT in that case.
The rest of the changes are simply making sure that the various
call points up the call stack don't print a warning message if
NS_ERROR_ABORT is returned up from
PrintTargetWindows::BeginPrinting.

Before we introduce PrintTargetEMF, all PrintTargets finish page printing task
before the end of PrintTarget::EndPage(). Unlike others, a page printing
in PrintTargetEMF is done after receiving an async callback from the pdfium
process. So we have both async and sync page printing behavior now. This patch
is trying to make both of them work correctly while priting a content document.

This allows us to fire MozMouseHittest events from tests and then read
the hittest result from the compositor APZTestData. The MozMouseHittest
event was chosen in particular because the existing uses of it are
similar in nature - it is a dummy event that is used to determine what
elements a particular coordinate targets. It is also an event that is
never generated by the OS and so using this event gives us more control
over what ends up in the APZTestData.

The core of this change is in gfxContext.*:
- change gfxContext::CurrentMatrix() and gfxContext::SetMatrix() to
return and take a Matrix respectively, instead of converting to
and from a gfxMatrix (which uses doubles). These functions therefore
will now match the native representation of the transform in gfxContext.
- add two new functions CurrentMatrixDouble() and SetMatrixDouble() that
do what the old CurrentMatrix() and SetMatrix() used to do, i.e.
convert between the float matrix and the double matrix.
The rest of the change is just updating the call sites to avoid round-
tripping between floats and doubles where possible. Call sites that are
hard to fix are migrated to the new XXXDouble functions which preserves
the existing behaviour.

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.

This patch was mostly[1] automatically generated. I found the files to be fixed
in this patch with the following command:
grep -r "C++; indent-tabs-mode:" gfx
...and then I modified each of these files with the following script
(where $1 is the filename to be modified):
###
old="/\* -\*- Mode: C++; indent-tabs-mode: nil; c-basic-offset: 4 -\*- \*/"
new="/\* -\*- Mode: C++; tab-width: 8; indent-tabs-mode: nil; c-basic-offset: 2 -\*- \*/"
sed -i s%"^$old"%"$new"% $1
###
[1] NOTE: Nearly all of these files use 2-space indentation, so it's correct
(from a consistency perspective and a reflecting-reality perspective) that
we're reducing their "c-basic-offset: 4" down to "c-basic-offset: 2" here. The
one exception is nsDeviceContext.h, which *does* actually use 4-space
indentation right now -- so I'm leaving that file with "c-basic-offset: 4" in
its mode line. This manual change (reverting 1 character from the automated
process) is the only piece of this patch that isn't automated.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

Most of this patch is updating a few places that use gfxMatrix to use
the equivalent-but-differently-named functions on MatrixDouble:
- Translate/Rotate/Scale get turned into PreTranslate/PreRotate/PreScale
- Transform(Point) gets turned into TransformPoint(Point)
- gfxMatrix::TransformBounds(gfxRect) gets turned into
gfxRect::TransformBoundsBy(gfxMatrix).
- gfxMatrix::Transform(gfxRect) gets turned into
gfxRect::TransformBy(gfxMatrix).
The last two functions are added in this patch as convenience wrappers
to gfxRect instead of Matrix.h because we don't want Matrix.h to "know"
about gfxRect (to avoid adding gecko dependencies on Moz2D). Once we
turn gfxRect into a typedef for RectDouble these will be eliminated
anyway.

nsIFontEnumerator::GetDefaultFont() returns always nullptr. However, it's used in font setting UI at creating drop down list of available fonts. So, if we implement this as returning first available font of "font.name-list.*", it's what is the necessary UI for "default" font when "font.name.*" is empty string.
So, with this patch, the top item of font list becomes "Default (%s)" if there is available font.

Since font-language-override can only have a single three-letter tag, and it is
eventually converted to uint32_t while creating gfxFontStyle, we should be able

nsFont::Init was created to be shared in two different constructors.
However, we could simply perform initialization in nsFont by Struct
Initialization and get the same effect.
The only primitive type that is not taken care of by nsFont::Init is
nsFont::size. Since nsFont::size represents the logical size of the font,
I think initializing it to '0' should be fine.

part 1: make all methods 'const' for the abstract class of PropertyProvider.
part 2: make nsFontMetrics's StubPropertyProvider final.
part 3: make nsTextFrame's PropertyProvider final.
Make some methods 'const' and some variables 'mutable', so we could let all the
overridden methods stay const.
We also need to make the pass-in parameter of gfxFontGroup's GetHyphenWidth const.
Note that the comment of GetHyphenWidth seem outdated, so I fixed it as well.
part 4: make the member variables in nsTextFrame's PropertyProvider to be 'const'.
Make all the member variables 'const' except mStart, mLength,
mJustificationArrayStart, and mJustificationSpacings.
The static function AdvanceToNextTab is fixed since we only use 2 of the 4 parameters.

We want the maximum scroll position to be aligned with layer pixels. That way
we don't have to re-rasterize the scrolled contents once scrolling hits the
edge of the scrollable area.
Here's how we determine the maximum scroll position: We get the scroll port
rect, snapped to layer pixels. Then we get the scrolled rect and also snap
that to layer pixels. The maximum scroll position is set to the difference
between right/bottom edges of these rectangles.
Now the scrollable area is computed by adding this maximum scroll position
to the unsnapped scroll port size.
The underlying idea here is: Pretend we have overflow:visible so that the
scrolled contents start at (0, 0) relative to the scroll port and spill over
the scroll port edges. When these contents are rendered, their rendering is
snapped to layer pixels. We want those exact pixels to be accessible by
scrolling.
This way of computing the snapped scrollable area ensures that, if you scroll
to the maximum scroll position, the right/bottom edges of the rendered
scrolled contents line up exactly with the right/bottom edges of the scroll
port. The scrolled contents are neither cut off nor are they moved too far.
(This is something that no other browser engine gets completely right, see the
testcase in bug 1012752.)
There are also a few disadvantages to this solution. We snap to layer pixels,
and the size of a layer pixel can depend on the zoom level, the document
resolution, the current screen's scale factor, and CSS transforms. The snap
origin is the position of the reference frame. So a change to any of these
things can influence the scrollable area and the maximum scroll position.
This patch does not make us adjust the current scroll position in the event
that the maximum scroll position changes such that the current scroll position
would be out of range, unless there's a reflow of the scrolled contents. This
means that we can sometimes render a slightly inconsistent state where the
current scroll position exceeds the maximum scroll position. We can fix this
once it turns out to be a problem; I doubt that it will be a problem because
none of the other browsers seems to prevent this problem either.
The size of the scrollable area is exposed through the DOM properties
scrollWidth and scrollHeight. At the moment, these are integer properties, so
their value is rounded to the nearest CSS pixel. Before this patch, the
returned value would always be within 0.5 CSS pixels of the value that layout
computed for the content's scrollable overflow based on the CSS styles of the
contents.
Now that scrollWidth and scrollHeight also depend on pixel snapping, their
values can deviate by up to one layer pixel from what the page might expect
based on the styles of the contents. This change requires a few changes to
existing tests.
The fact that scrollWidth and scrollHeight can change based on the position of
the scrollable element and the zoom level / resolution may surprise some web
pages. However, this also seems to happen in Edge. Edge seems to always round
scrollWidth and scrollHeight upwards, possibly to their equivalent of layout
device pixels.
