Bug 1635658. Fix how CSS filters render with webrender that are represented as component transfer when they are required to be represented as SVG filters. r=mstange a=pascalc

The brightness, contrast, and invert css filters are represented as component transfer filters when they required to be represented as an svg filter (ie when an element has a combination of CSS and SVG filters specified).

https://hg.mozilla.org/mozilla-central/rev/4f3360c4f104 (bug 1417699) used the value SVG_FECOMPONENTTRANSFER_TYPE_UNKNOWN for the function type in the G and B channels to specify that the R channel function should be used. As we know from https://hg.mozilla.org/mozilla-central/rev/a1ff0af83ad2 (bug 1605223) SVG_FECOMPONENTTRANSFER_TYPE_UNKNOWN is the value we get if the function is not specified, and by spec that is to be interpreted as the identity function.

To fix this use a special function type that is not exposed to content, SVG_FECOMPONENTTRANSFER_SAME_AS_R, when we want to do this optimization. And then teach the webrender filter code to understand it.

Bug 1618345 - Enforce proper color management by splitting gfx::Color into sRGBColor and DeviceColor types. r=jrmuizel

gfx::Color is currently misused in many places. The DrawTargets expect
the color space to be in device space, e.g. what we are actually going
to draw using. Everything sitting above generally deals with sRGB, as
specified in CSS. Sometimes we missed the conversion from sRGB to device
space when issuing draw calls, and similarly sometimes we converted the
color to device space twice.

This patch splits the type in two. sRGBColor and DeviceColor now
represent sRGB and device color spaces respectively. DrawTarget only
accepts DeviceColor, and one can get a DeviceColor from an sRGBColor via
the ToDeviceColor helper API. The reftests now pass with color
management enabled for everything (e.g. CSS) instead of just tagged
raster images.

There will be a follow up patch to enable color management everywhere by
default on all supported platforms.

Ran into a couple of test failures because I was leaving
mAttributes empty for empty things like MergeAttributes, and
only setting mType. Since mType is now redundant though, and
since it's the only use of PrimitiveType, I figured I'd just
remove it entirely.

This replaces the hash map of attributes with a tagged union. In
this case, all filter attributes will be stored in line, with the
exception of some more complex attributes which have an internal
nsTArray of floats. This should help avoid all the hashing and
extra heap allocations.

Bug 1412346 part 5: (automated patch) Switch a bunch of C++ files in layout to use our standard mode lines. r=jfkthame

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.
