In the future we're going to want VideoBridge connections from the RDD process into both the parent process and the GPU process.
This does the preparation work for unifying the way we create VideoBridges (using Endpoints, required for cross-process connections),
and detects which one to use based on where the video will be composited.

Gecko layouts typically produce a picture cache where the origin
of the picture rect is an integer. However, it can occasionally
be a fractional origin.
In these cases, we need to ensure the content origin is floored,
to maintain consistent snapping. When this case occurs, the UV
rect for the tile also needs adjusting, to ensure the exact
1:1 texel:pixel mapping when drawing the tile.

Static VarCache prefs have setters. These are dangerous because they can

Fortunately they are only used in tests, and we can use vanilla pref setters
instead, and get rid of the VarCache setters.

This is a simple mach command that imports a PR from a whitelisted set
of github repositories into the local m-c clone. It works by downloading
the .patch file from github, splitting the different commits, and
applying those commits to the local repo via the `patch` tool and git/hg
commit. It optionally allows filing a bug or providing a bug number, and
specifying a reviewer.
This is one part of a larger workflow that facilitates landing
contributor patches into m-c when those patches are submitted as PRs.
Other components of the workflow (to be added in the future) will make
it easier to actually test and land the patch.

This changes CreateClippedDrawTarget so that instead of taking
a max size and a transform it just takes a user space rect of
the desired bounds.
This change allows the caller to not worry about the computing
a max size based on the current clip. Instead this responsibility
is lowered into the specific backends.
The main motivation for this work is to allow blob recoordination
to create recordings that don't depend on the current clip.
Some additional benefits are that the API is easier to use and
as can be seen simplifies the SVG masking code because it doesn't
need to track surface offsets manually.
It's also an important step towards removing all the uses of
gfxContext::GetClipExtents which will let us get rid of the separate
clipping stack in gfxContext and help us move off of gfxContext
completely.
Most backend implementations of CreateClippedDrawTarget are relatively
simple. DrawTargetCapture is modified to track the current clip rect
so that it can create a new DrawTargetCapture of the appropriate size
without needing to worry about lazy resolution.

There's two things going on here. 1) nsGfxScrollFrame is getting the
wrong renderroot, because it's not correctly recursing up the frame
tree. 2) Hiding behind that problem is that if we do correctly assign
the renderroot, we end up blocking on both render roots updating if
we don't, say, have a horizontal scroll option, because that leaves
us with a wr::RenderRoot::Default. 2.1) We then still end up blocking
on the default renderroot because we initialize the selector with
WebRenderBridgeParent's mRenderRoot.

This patch fixes two issues with blob images + new picture caching.
1) The logic that determines a conservative set of visible tiles
for tiled / blob images was no longer correct. It was relying
on the bounds of a single tile to build the conservative rect.
Instead, take the overall primitive world bounds and derive a
conservative set of visible tiles from this.
2) The logic to detect if an image was dirty was incorrect, and
somewhat error prone. It now maintains a set of dirty images
that have been requested. The image key dependencies are then
checked during the tile cache post_update step.

ImageBridgeChild has only one global TextureFactoryIdentifier. When WebRender is enabled, it is used for both WebRender widget and non-WebRender(BasicCompositor) widget. WebRenderImageHost and ImageHost are incompatible and WebRenderTextureHost does not permit to be consumed on compositor thread. Then it does not work well for non-WebRender widget. To address the problem at ImageContainer, ImageContainer needs to know a connected widget type. It is not easy in some cases like WebRTC. Then host side could address the problem easier.
CompositableParentManager::FindCompositable() is changed to permit transform from WebRenderImageHost to ImageHost if it is necessary when WebRenderImageHost belongs to ImageBridge.
WebRenderTextureHost is changed to permit to consume wrapped TextureHost on compositor thread. If the wrapped TextureHost is BufferTextureHost, it is possible to comsume the TextureHost on compositor and on RenderThread, since they are memory buffer or shared memory buffer. WebRTC code always create BufferTextureHost for video frame. Then it works.
