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.

To use GetCSSPxToDevPxMatrix in nsFilterInstance, pull this untility function down
to nsSVGUtils; Otherwise, we have to include nsSVGIntegrationUtils header in
nsFilterIntance, which is ok but not good I think.

1. Rename these functions to agree with Mozilla coding style.
2. Use singular naming instead of plural naming since each of these functions
returns an iterator pointing to a singular line.
3. Rename line() and rline() to BeginLineFrom() and RBeginLineFrom(), which
shall improve the readability.

Otherwise, when a glyph changes, we might end up doing too much work, destroying
the text-run and the observer that dirtied the frame, causing an assertion when
trying to delete it from the observer set.

Although this makes some places more complicated, code should generally
be simpler and clearer. It could slightly improve performance on x64 for
functions with more than four parameters, since it makes more data be
passed via registers rather than the stack.
