Flickering happened when SharedSurface_ANGLEShareHandle is destroyed before RenderDXGITextureHostOGL::EnsureLockable() is called on Render thread. RenderDXGITextureHostOGL failed at device->OpenSharedResource() . In this case, SharedSurface_ANGLEShareHandle failed to render. Then black was rendered.
If TextureClient::CancelWaitForNotifyNotUsed() is not called, the refcount is kept until the host side ends its usage. The refcount is removed by CompositorBridgeChild::NotifyNotUsed().
Depends on D33265

CancelWaitForRecycle() does not cancel wait for recycling. It cancels wait for end of usage on host side.

gfxPrefs Live preferences are almost identical to StaticPrefs.
We leave aside for now those that set a custom change callback as this feature isn't yet supported in StaticPrefs.

* Remove redundant virtual keywords
* Mark all destructors of inheriting classes as virtual for clarity
* Mark all classes without virtual destructor as final (exposed errors)
* Make destructor virtual where it needed to be (some were missing)
* Replace empty ({}) code declaration in header with = default
* Remove virtual unused methods
I probably missed some, it quickly became a rabbit hole.

It would have been nicer and more logical to use a MacIOSurfaceImage to store the colorspace information, however the data passed around is a IOSurface Id via a SurfaceDescriptorMacIOSurface; the original data structure isn't kept; so we must transit the data at the same time as the IOSurface Id.
Also remove unnecessary test (new operator is infallible).

YUVColorSpace is inseparable from the bit depth as the matrix coefficients to be calculated need the bit depth information.
So let's put the two types together. gfx namespace also makes more sense as that's where we find IntRect, IntSize and other.
The extent of the changes highlight how much similar data structures are duplicated across the code, to the point it's scary.

The only platforms that do not support GL_PACK_ROW_LENGTH are platforms with
GLES 2. So on those platforms, trying to read back into buffers whose stride is
not width * 4 will assert.
That's fine because we usually don't encounter buffers with such large strides
on GLES 2 platforms. The only platform that really needs to handle the large
strides is macOS, and it always supports GL_PACK_ROW_LENGTH.
On macOS, we often run into large strides on surfaces that we intend to upload
as textures at some point, because large stride alignments are required for
efficient upload performance on some drivers.
Bug 1540209 tracks fixing the general case.

On Wayland with WebRender, RenderCompositorEGL creates headless context by using GLContextProviderEGL::CreateForCompositorWidget(), since GetNativeData(NS_NATIVE_EGL_WINDOW) returns nullptr. But we want to make hadless explicitly. But GLContextProviderEGL::CreateHeadless() and GLContextEGL::CreateEGLPBufferOffscreenContext() could not be used for it. They creates incompatible EGLConfig to egl window. Then we extends GLContextProviderEAGL::CreateForCompositorWidget() to handle this case. When CreateForCompositorWidget() receives null widget, it creates GLContext without surface of egl window.

EGLConfig could be get from GLContextEGL. It is better to use it than re-creating EGLConfig.
