Audit all the types related to app units [1] printed in
nsIFrame::List (and all the methods that override it), and use
ConvertToString to convert their printing format to CSS pixels if
needed.
In addition, add operator<< to BaseCoord so that it can cooperate with
mozilla::ToString, which is needed by ConvertToString.
[1] The types include nsRect, nsSize, nscoord, LogicalRect, and
LogicalSize.

Previously, primitive dependency checking would invalidate a tile if
the spatial node index for a given primitive changed.
However, if a new display list is sent that changes the shape of
the spatial node tree this may cause unnecessary invalidations.
For example, a new display list that inserts a new spatial node at
the start of the tree could result in spatial node indices being
different, even though the values of the transforms was the same.
This patch changes the invalidation logic for spatial nodes to
compare the transforms by value, rather than index, meaning that
invalidations are avoided if the shape of the spatial tree has
changed, but the values are consistent.

The `sampleInUvRect` function in `gfx/wr/webrender/res/cs_svg_filter.glsl` calls
`texture`, passing the optional third argument that specifies a bias to the
sampler's level-of-detail calculation, used for mipmap interpolation. However,
the `texture` override in `gfx/wr/swgl/src/glsl.h` that accepts this parameter
is stubbed out, with an `assert(0)`. This causes twelve tests in
`gfx/wr/wrench/reftests/filters` to crash.
Nothing in Firefox uses mipmaps, and Servo doesn't use Software WebRender, so it
should be fine for that call to `texture` to simply not pass the level-of-detail
bias.
This patch makes that change.

TabGroup never really made any difference in which thread something go
dispatched to. This was the intended use, but development of TabGroups
with abstract main threads never made it that far. The good thing is
that thish makes it safe to also remove to the SystemGroup and instead
switch all SystemGroup dispatches to dispatches to main thread.
Timers for setTimeout and workers were the sole users of wrapped and
throttled event targets, that those throttled queues have been moved
to the BrowsingContextGroup and are now accessed explicitly.
The SchedulerEventTarget has been removed, since there are no longer a
separate event target for every TaskCategory. Instead a
LabellingEventTarget has been added to DocGroup to handle the case
where an event is dispatched do DocGroup or when an AbstractThread is
created using a DocGroup. This means that we'll actually label more
events correctly with the DocGroup that they belong to.
DocGroups have also been moved to BrowsingContextGroup.

To be able to remove SystemGroup, NS_ReleaseOnMainThreadSystemGroup
needs to have its dependency on SystemGroup removed. Since all
releases using SystemGroup would've released on the main thread anyway
we can safely replace NS_ReleaseOnMainThreadSystemGroup with
NS_ReleaseOnMainThread.

In mozilla::ipc::SharedMemory, the memory() method was virtual, so we cached the address here
(although the compiler would likely have inlined the accessor as the `final` concrete subclass
was known). Anyhow, in base::SharedMemory it's a trivial (non-virtual) accessor, so there's
no sense in shadowing it here.

The base::SharedMemory class provides APIs to create a "read-only" copy of a shared memory block,
which means it can be shared to a child process without the risk that the child might map it as
writable and corrupt the contents. We want to use this facility for the font list, hence switching
the shared-memory APIs used.

For Win32k lockdown, we need to remove the content processes' ability to
call GetICMProfileW(). Since it needs this to retrieve the output color
profile, a new synchronous call is added that allows it to request the
parent process to read this file on its behalf.
The contents of the file are now being cached as well, as this should help
ease some of the increased parent process I/O caused by the children not
being able to do this in their process anymore.
For performance reasons, during launch this information is passed directly
to the child through the SetXPCOMProcessAttributes call

The picture cache code retains a set of tiles that are currently
off-screen but might be needed again soon, depending on how the
page is scrolled.
However, off-screen tiles were being skipped during draw processing,
which meant that the texture cache request method was not being
called on these tiles. This would often result in the texture
cache eagerly evicting these seemingly unused surface tiles.
This patch re-arranges the occlusion and visibility processing
code for tiles, so that if a tile has been retained in the
picture cache grid, the texture surface is always requested,
even if that tile is currently off-screen. This prevents the
texture cache from evicting tiles that we want to retain for now.

this is an attempt to handle tasks outside of the device bounds,
that belong to surfaces not establishing raster roots.
I suspect that the scaling we are now setting up in adjust_scale_for_max_surface_size
doesn't work properly, since the function was assumed to only affect the raster-rooted
surfaces. But it does fix the crash we have.
