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.

Summary:
The implementations of most SVGTextElement methods flush layout when they're
called. Any SVG <text> that is displayed normally will be reflowed by
SVGTextFrame::ReflowSVG, and any <text> that is in displayed SVG but is not
displayed directly (such as <text> under a <defs>) will be reflowed by
SVGTextFrame::ReflowSVGNonDisplayText. Prior to this fix the changed
code always assumed that one of these methods would reflow the text. However,
in the case that the SVG is under an HTML element that isn't itself ever
reflowed (such as if it's under an HTML <caption>) then the SVG text will
not be reflowed either and the invariants of the code are broken.
This patch modifies the functions that implement the SVGTextElement
methods to return an error code if the text has not been reflowed.
Note: I did try to reuse SVGTextFrame::ReflowSVGNonDisplayText in this
case, but I ran into problems. Given that this is an edge case and likely one
than normal authors will never run into I gave up trying to make that work for
now.

Bug #: 1402109
Differential Revision: https://phabricator.services.mozilla.com/D107
(Path is actually r=froydnj.)
Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

All classes which have mCanvasTM declared as a member object are inherited from
nsSVGDisplayContainerFrame. We should just declare a protected member in the
base class and then remove mCanvasTM and duplicated implementaion of
GetCanvasTM & NotifySVGChanged in those derived classes.

Unless we need to draw stroke of glyphs, which will change the state of the
target context, we only need to save & restore transform matrix of the target
context.

nsDisplaySVGText::Paint calls SVGTextFrame::PaintSVG, and we already save/restore
context state in SVGTextFrame::PaintSVG.
I also filed Bug 1385929 to find a solution to prevent duplicated
gfxContext::Save/Restore.

One thing to note here is that the Scale function on gfxRect has a
different implementation than that in gfx::Rect which is replacing it.
The former just scales the width/height directly whereas the latter
scales the XMost/YMost and recomputes the width/height.

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.
