A spatial id of 0 refers to the root reference frame on the WR side, but
we shouldn't be using that on the Gecko side at all. Due to the
early-exit codepath in ClipManager we were actually sending some display
items with this spatial id over to WebRender. Although this doesn't
appear to cause any user-visible problems it seems wrong and can confuse
debugging other issues.

The main change here is removing some rounding so that we can do more
accurate hit-testing in APZ. Instead of rounding both the rect and the
point, we just store both as unrounded values. mRenderRootRects is also
changed to be of a Screen type as that better reflects what it's being
used for, and there is a legitimate justification for converting it from
LayoutDevice.

We use a strongly typed LayoutDevice rect because that's the correct
type for this rect. And we defer the rounding to the parent side for
more precise hit-testing (see next patch).

The receiver of this parameter treats it as a layout size, so it doesn't
make sense for the argument to be a LayerSize partway through the call
chain. Also the callers originally get this from a LayoutDevice rect;
so there's even less reason for this to be turned into a LayerSize. The
next patch will propagate this cleanup more.

If we try to send them separately as we were before, we can run into
cases where we try to destroy the actors and then send the OpRemoveTexture,
which crashes.

`gecko_profiler_add_text_marker` was being passed a character pointer and a
length to construct a `nsDependentCString`. However, these values were coming
from a Rust `&str`, which is not null-terminated, causing an debug assertion to
be hit (and possible memory safety issues if mishandle the string). We now
construct an `nsDependentCSubstring` instead.

By Bug 1526213, WebRenderBridgeParent::RecvEmptyTransaction() does not handle a case that resource update is handled by WebRenderTextureHostWrapper. In this case, txn.IsResourceUpdatesEmpty() became true and the function thought there was no resource update and the function returned DidComposite soon to client side. Then it caused a heavy over production of SharedSurface_ANGLEShareHandle if GPU is not powerful.

The way we control APZ zooming in WebRender is by inserting an animation
property placeholder on a WR stacking context, and then having APZ
update the animation transform value with the proper matrix at composite
time.
Previously, the stacking context being used was the rootmost
stacking context in the content process. However this doesn't work for
zoomable content in the UI process (e.g. about:support), and after
recent changes, also wraps display items that should not be affected by
zoom (e.g. scrollbars or the background color item).
This patch moves the animation property placeholder so that it
corresponds to the newly added nsDisplayAsyncZoom display item, which
corrects both of the above problems and is conceptually in line with the
desired behaviour.

The goal of this change was to simplify the semantics of our document placement and split the logical elements inside (display list) from the actual screen rectangle occupied by a document.
To achieve that, we introduce the framebuffer space for things Y-flipped on screen.
We fix the frame outputs, so that they get produced on the first frame without loopback from the frame building to scene building.
