This patch changes a few things:
* Restores clipping to the computed clip, but just for SVG filters.
* Computes the clip just from the primitive subregion, not the bounds of the filtered content.
* Unconditionally clips all SVG filters using the primitive subregion
* Allows clips to be combined, if they will be sharing a coordinate space
* Fixes coordinate space of the clip region.

In the case of an invalid clip-path, the browser is supposed to discard the
mask entirely. In the non-webrender codepath this would happen
implicitly because the computed MaskUsage would have no flags set, and
so no actions would be taken on the gfxContext which contained the
display items rasterized so far. In the WebRender codepath, though, we
invoke the code on a A8 drawtarget that's zero-filled, so if PaintMask
fails to rasterize anything into it, it gets treated as a "mask everything
out" mask. Instead, this patch makes it so that we detect the scenario
where the computed MaskUsage is a no-op, and ensure that we don't apply
the mask in that case.
An alternative approach considered was to initialize the A8 drawtarget to
white instead of black but in cases where there is an actual mask, the
rest of the code assumes it is zero-filled and so that doesn't work.

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.

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.

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.

We need this new function to determine whether paint mask onto mask layer.

Two reasons that we should do this:
1. Make PaintMaskAndClipPath even simpler.
2. We need this new function to determine LayerState of a nsDisplayMask later.
