This patch allows us to intercept invalidation requests for display
items, and avoid regenerating the display list for animated images which
are using SharedSurfacesAnimation.

Animated images inside of SVGs and used in XUL frames did not get the
configured animation image mode from the pres context.

When generating display lists for WebRender, we were not caching the
draw result via nsDisplayItemGenericImageGeometry::UpdateDrawResult (or
similar) after completing CreateWebRenderCommands. This is important
because reftests use this to force sync decoding for images; it may be a
reason for image-related intermittent failures on *-qr builds.
Additionally, we may have been requesting fallback in cases where fallback
could not do anything more than WebRender could. For example, if we can't
get an image container yet, there is no point in requesting fallback
because it might just be we haven't started decoding yet. We should just
return the actual draw result in such cases.
In addition to the image container, the draw result can also be useful
for callers to know whether or not the surface(s) in the container are
fully decoded or not. This is used in subsequent parts to avoid
flickering in some cases.
Introduce an ImageRendering argument for CreateImageKey which is then used at the CreateAsyncImageWebRenderCommands call to provide the proper filtering instead of using always Auto filtering. Update all calls to CreateImageKey to use the new interface.
When the frame updates for an animated image, it will trigger
nsImageBoxFrame::OnFrameUpdate to be called. We did not change this for
WebRender, and thus it was missing similar checks added to
nsImageFrame::InvalidateSelf as originally added in bug 1382985. This
caused us to ignore the frame update, and thus the animation never
appeared to progress.
This builds on bug 1428676 and introduces StyleAppearance, which replaces the
NS_THEME_* constants.
Really sorry for the size of the patch.
There's a non-trivial change in the gtk theme, which I submitted separately as
bug 1478385.

Vector images don't support image containers if they are animated. In
order to support this with WebRender, we would need to know when the
generated shared surface was composited, so that we can update the image
container on the next refresh tick. Because images use a different code
path (not ImageClient), we don't have the ability at present. Changing
vector images naively and just updating on every refresh tick if there
is an image container to avoid fallback causes the animation to be very
janky.
Given nsImageFrame is already using fallback properly in this situation,
then we can just fix nsImageBoxFrame to do the same. This gives
acceptable performance without any visible slowness on the animation.
And then fix up everything else that needs to change as well.

This function doesn't use any StackingContextHelper state anymore.
We should make what it does clearer and move it to a better place.

When we fail to generate an image key for an image, it is likely because
the image container is empty. This is not a fatal error, it just means
we haven't produced a frame yet. We should be using NOT_READY instead of
BAD_IMAGE as a result. This is important because reftests rely upon
these error codes to know whether or not they should wait; it could
cause intermittent failures.
-Wmissing-prototypes is a new optional warning available in clang ToT. It warns about global functions that have no previous function declaration (e.g. from an #included header file). These functions can probably be made static (allowing the compiler to better optimize them) or they may be unused.
Confusingly, clang's -Wmissing-prototypes is equivalent to gcc's -Wmissing-declarations, not gcc's -Wmissing-prototypes. A function prototype is a function declaration that specifies the function's argument types. C++ requires that all function declarations specify their argument types, but C does not. As such, gcc's -Wmissing-prototypes is a C-only warning about C functions that have no previous function *prototypes* (with argument types), even if a previous function *declaration* (without argument types) was seen.

It would be convenient to get nsPresContext from nsIDocument.
