This implementation is off by default (behind gfx.webrender.compositor) until
various bugs and inefficiencies are fixed. See bug 1592016.

This allows us to somewhat cheaply swap out the entire set of layers.
It also means that clearing the array of layers no longer has quadratic complexity;
in the past, you would do this by calling RemoveLayer once per layer, and RemoveLayer
does a linear scan through the array.

This change makes opaqueness a boolean per layer again. The opaque region is
currently only used by the temporary WebRender code; the future WebRender code
won't use it. Removing this support simplifies the code and makes it easier to
implement clipping.

This prevents stale indices into the prim visibility scratch
buffer being reused on subsequent frames, which can cause various
unexpected code paths to be hit.

The recorder can still contain UnscaledFonts, but they are never removed
currently, so we can't wait for them and they will be re-recorded safely anyway.

The patch permits to resize compositor window's size after ::SetParent() call to prevent a conflict between ::SetParent() and ::SetWindowPos(). Then it triggers a composite after SetParent() call to resize compositor window correctly.

When JS is paused, VRService will automatically shutdown because the timer is not updated,
we used to create a new VRDisplay to JS. However, the page is still using the older VRDisplay,
so it can't get the newest VRDisplayInfo status. We should exit presentation and
apply the VRDisplayInfo status to the original VRDisplay instead of creating new one.
Besides, we also need to release the VR screen buffer after exiting the immersive mode to avoid eglMakeCurrent error.

This passes the existing dirty rect for a picture cache update
through the native compositor interface, allowing compositors
to only update a sub-rect of a tile.
Also update the example to pass dirty rect to DirectComposition,
and add debug drawing for compositor redraw region.

Platform differences between DirectComposition and CoreAnimation
mean that WR needs to bind the FBO ID that the underlying platform
returns as part of the surface binding operation.

This patch is a small refactor of the public and internal structures
for options related to partial present and native compositing. It
doesn't contain any functional changes.
It adds a field to the native compositing setup to allow clients to
express whether dirty rect updates are supported when native compositing
is enabled (not currently used but will be enabled soon).
It also removes the partial present config options, and makes them
part of the default / draw compositing mode.

EGL_ANGLE_experimental_present_path was enabled for fast rendering to SwapChain by ANGLE. But current gecko does not request ANGLE to render to SwapChain for WebRender. Then we do not need to use EGL_ANGLE_experimental_present_path anymore. But Its usage still has a side effect that y is flipped. But OS compositor implementation on Windows does not want it. And it seems not good to continue to use EGL_ANGLE_experimental_present_path since it is experimental feature.
But when EGL_ANGLE_experimental_present_path is removed, rendering result of frame buffer is y flipped with ANGLE compared to other OpenGL implementation. It needs to be handled in WR. It is similar to chromium.

With this patch, picture cache slices are constructed each time
a new scroll root is established. This reduces rasterization
cost on pages that have large fixed position elements, and pages
that contain multiple scroll roots.

VRManager only be accessible in the parent or GPU process. So, in the tab process, isPresenting() will always return false. In WebVR immersive mode, we need to skip layer painting and don't need to wait for painting because the compositing is already done in WebGL.

This issue happens when VR/GPU haven't connected with the parent process via IPC protocol, and we are trying to access its IPC Child when it is still null. It is possible to be happened when GPU/VR process is killed/shutdown, and we are trying to launch a new VR process. We need to check these status before completing our VR process's launch.
