This provides glyph-extents support for these fonts, so that fallback diacritic positioning can work.
In principle we could try switching to the hb_ot_font functions for all fonts, but this carries
some risk of disrupting other issues: (1) on some platforms, our glyph-advance callbacks use platform
APIs rather than reading the font file directly, in order to respect hinting that may be in effect;
and (2) the hb_ot_font functions don't currently provide fallbacks for CJK Compatibility Ideographs
Standardized Variants, as implemented for Gecko in bug 989557, so that case would be regressed.
Hence, for the time being switching only for OpenType/CFF fonts, where the thebes callbacks are
known to be incomplete (no glyph-extents support) is the safer, more conservative approach.

Using `ccache` apparently interferes with how flag checking is done when
we're using `clang` as our compiler. We can work around this by adding
a few more flags to flag checking.

This won't reintroduce any of the regressions that were triggered by our
previous attempts to turn off -moz prefixed gradients, and lets us massively
simplify the gradient code, if it sticks.

Bug 1052579 introduced a new mozjemalloc arena for JSString char buffers.
Unfortunately, my testing missed the case where JSStringBuilder causes an OOM
condition, causing the OOM handler to realloc to the default arena, regardless
of what arena is actually indicated by the AllocPolicy for the char vector.
The realloc now passes the arena from the AllocPolicy to mozjemalloc.

These are added in start, and we get into unexpected state if they notify us
after Stop() (when MediaEncoder shuts down and internally removes the tracks
it is encoding) but before Shutdown() when we remove the listeners. This is not
symmetrical. The proper thing to do is to remove these listeners in Stop() as
well.

I removed WeakRef since this is already very close to WeakHeapPtr and is an alias of it. I think having the two is more confusing than using the same name for both (the difference is whether you trace it with TraceWeakEdge or sweep it in a more manual fashion).

Historically we calculated the snapping offsets in the GPU shaders.
Because this information is always needed on the CPU side, we now just
pass the values into the shader instead of recalculating again. This
ensures we will use the same set of values consistently and makes it
easier to adjust how we snap in the future.
This patch should have no functional change on the output of WebRender
itself.

We currently do most snapping on the GPU in the shader. However the
picture's local rect needs to take into account the snapping done there,
so we need to calculate this earlier in the pipeline. Instead of using
the clipped primitive local rects to create the picture's own local
rect, we now snap the child local rects first. If no snapping is
required, there should be no functional change. If snapping is required,
there should be fewer visual distortions caused by an inaccurate picture
local rect.

We currently calculate a picture's local rect when we are doing the
first picture traversal. It was composed of the union of the clipped
local rects of its children. However the true local rect of a picture is
the union of the snapped clipped local rects of its children. The
snapping is done in device space, but we won't know the exact transform
until we establish the raster roots, which is based on the picture's
local rect.
As such, we create an estimated local rect which is how we currently
calculate the local rect. Then once the raster roots have been selected,
we recalculate the local rect of the picture based on its children
during update visibility.
This patch should have not contain any functional changes.
