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.

The reason of this change is the same as for Part 2, except that this commit fixes
nsSVGPaintServerFrame::GetPaintServerPattern rather than PaintSVG.

The DrawResult return was not in fact anything to do with the success or
failure of that method, but was actually passing out a very specific piece of information
about the success or failure of any imagelib drawing that may not have occurred
under the various PaintSVG calls.
The signature of PaintSVG is changed from
DrawResult PaintSVG(...., uint32 flags);
to
void PaintSVG(...., imgDrawingParams& aPackage);
imgDrawingParams wraps DrawResult and imgIContainer::FLAG_* as a pack, pass through
PaintSVG to imagelib draw calls under beneath.

Add one paramater to nsSVGDisplayableFrame::PaintSVG, so that we can pass
sync-decode flag from nsXXXXDisplayItem::Paint function to SVG paint call.

According to bug 1345853 comment 5, tn said:
You probably want to return whatever was drawn there regardless of the
DrawResult. SVGMaskFrame has the same problem. Keep in mind that DrawResult is
only reporting on how drawing of any images went, not the drawing of anything
else. Also looking over the patches from bug 1258510 I see a couple places where
BAD_ARGS is returned if the transform matrix is singular. We would want to
return SUCCESS in that case I think, because we drew what we were instructed to
draw.

I did many change in many files in this patch. But the goal is pretty simple: To
pass the return value of nsSVGPatternFrame::PaintPattern back to the caller
(nsDisplaySVGGeometry). My suggestion is to review this patch right from
nsSVGPatternFrame.cpp.
I made two mistakes in bug 1258510
1. We should not return directly at [1]. RemoveStateBits at l418 will be skip.
2. nsSVGPatternFrame::PaintPattern should return both SourceSurface and draw
result, so that we can update UpdateDrawResult in display item.
All the other changes are to
1. make sure the return value of nsSVGPatternFrame::PaintPattern goes back to
nsDisplaySVGGeometry::Paint correctly.
2. Since the return value of nsSVGPatternFrame::PaintPattern change, we need
modify all existed callers.
I also filed bug 1346124 for handle the returning value of PaintMarkers.
