DisplayItemBuilder now has methods:
```
void StartGroup(nsPaintedDisplayItem* aItem);
void CancelGroup();
void FinishGroup();
bool ReuseItem(nsPaintedDisplayItem* aItem);
```
WebRender display items previously created between calls to StartGroup() and FinishGroup() will be reused by a call to ReuseItem(),
which will push DisplayItem::ReuseItem(key) to WR display list, if the Gecko display item has been retained and reused.
Calling CancelGroup() will discard the display items that have been pushed after calling StartGroup().
For example, inside nsDisplayBackgroundColor::CreateWebRenderCommands():
```
aBuilder.StartGroup(this);
aBuilder.PushRect(r, r, !BackfaceIsHidden(),
wr::ToColorF(ToDeviceColor(mColor)));
aBuilder.FinishGroup();
```

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.

This patch adds an asynchronous hit tester that can perform hit testing queries without blocking on a synchronous message to the render backend thread, which is often busy building frames. This is done by having a shared immutable hit tester readable by any thread, atomically swapped each time the render backend processes a new scene or frame.
In order to asynchronously hit test without causing race conditions with APZ intenral state, the hit tester has to be built while the APZ lock is held.

This removes the need for explicit #ifdef NS_BUILD_REFCNT_LOGGING without
introducing user-defined destructors when it is not defined.
Also, some uses of virtual for declaring destructors are replaced by the
appropriate override declaration through these changes.

We need a way to switch it on and off to compare the performance and power usage of various test cases.
The new pref is "webrender.enable-multithreading" and does not require a restart.

Optionally serialize N frames into a circular memory buffer, and save
them as part of wr-capture into tilecache/.
The new tile_view utility reads the folder and converts the frames to
svg for easier visualization, with a few extra features:
- color code each primitive based on which slice it is on;
- highlight new or moving primitives in red (brute force diff);
- print all invalidated tiles at the top and the invalidation reason;
- overlay the tile quadtree to visualize splitting & merging;
- HTML and JS wrappers for animation playback, timeline scrubbing;
Positioning of the tiles on the screen is a bit broken still; especially
during scrolling and "special" pages (like about:config).
Interning info is not used yet.

This patch only allows sacrificing subpixel anti-aliasing when the
screen size is larger than WUXGA, and when the force disable pref is not
set. In the future, we may also add disable this for high end GPUs.
This also consolidates the WebRender debug flags to use the same
signaling infrastructure to avoid needing to store the debug flag state
and check on each transaction. Instead it now applies the debug flag
updates when the gfxVar changes.
