There shouldn't be a local transform because we create container layers
for fixed layers, so any transform would be on a descendant layer instead.

In this process, TransformTo() and UntransformTo() are renamed TransformedBy()
and UntransformBy() so calls to them continue to read sensibly.

Call sites (all in APZ and related code) were modified accordingly. Some of
these modifications involved changing some matrices stored in APZ to be typed.

This requires adding a new overloading of LayoutDevicePixel::ToAppUnits and a
new PixelCastJustification: LayoutDeviceIsParentLayerForRCDRSF.

The untransformation is done using the newly added UntransformTo() functions
which call Matrix4x4::ProjectRectBounds(), which returns an empty rectangle
if the result is not at least partially on the positive side of the w = 0 plane.
UntransformTo() returnis the transformed rectangle if it's not empty, and
Nothing() otherwise, making callers check for this case.
The patch also adds some assertions to places where we apply transforms we
know should be 2D (and thus didn't switch to use UntransformTo()), checking
that the transforms are in fact 2D.

It shouldn't be checking the w coordinate of the difference of two Point4Ds. The 4D difference isn't really meaningful. Instead, it should be checking each point's w coordinate individually.

Whenever the inverse of a 3D projective transform is applied to a point, only use the result if it has a positive w-coordinate.
When transforming by a matrix that we know should be 2D, assert to that effect.
Transformations of rectangles (as opposed to points) remain to be audited.

When connecting a lowdpi external monitor on hidpi mac, TabChild gets an
UpdateDimensions call, followed by a UIResolutionChanged call. After
the UpdateDimensions call, the content process is in an incorrect state
where it has the dimensions of the new display and scale of the old one.
After the UIResolutionChanged message, the values are again consistent.
In the interim, reflow resizes layers based on the incorrect (old) scale
and subsequently uses those incorrect values when the new scale comes
in. This patch normalizes the message parameters by dividing by scale
(the result is what OS X calls point coordinates) so that this doesn't happen.

Change interface of getter/setter for mClipRect,
also necessary modification for codes that use these resources.

Bundle mUseClipRect and mClipRect as Maybe<ParentLayerIntRect> mClipRect
