We don't have lossy currentcolor in the style system anymore, except for a
single property -moz-font-smoothing-background-color.
I could've converted it into a proper StyleColor and thread down all the
necessary information to the font metrics code.
But it doesn't really seem worth it given it's not exposed to the web, so I just
did the simplest thing, which is making currentcolor compute to transparent to
that specific property.
This patch also removes the stores_complex_colors_lossily code and related,
since now we always can cache computed colors.

There are many bugs regarding our use of EffectSet::GetEffectSet(nsIFrame*)
because the intention of the caller is not clear. If it is called for the
primary frame of display:table content do we expect it to get the EffectSet
associated with the style frame or not? Generally it depends on if we are
looking for transform animations or not.
Rather than inspecting each call site and making it choose the appropriate frame
to use, this patch introduces a new method to EffectSet to get the appropriate
EffectSet based on the properties the caller is interested in.
This patch also uses this function in FindAnimationsForCompositor which in turns
fixes the glitching observed on Tumblr that arose since a number of places in
our display list code were passing the style frame to
EffectCompositor::HasAnimationsForCompositor.
Over the remainder of this patch series we will convert more callers of
EffectSet::GetEffectSet(nsIFrame*) to this new method before renaming
EffectSet::GetEffectSet to GetEffectSetForStyleFrame to make clear how the
method is intended to work.

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 API to create a sticky spatial node doesn't allow us to set a clip
chain that will apply to all the contents of the sticky node. This means
that when the ClipManager sets up the clip state for the sticky node,
the clip chain for it is dropped. Everything still works currently
because the contents of the sticky node have their own clip chains whose
parent link will include the sticky node's clip chain. However, in the
next patch we're going to sever that parent link to fix other issues,
and so we will break this mechanism. This patch fixes it up by
explicitly applying the sticky node's clip chain to the stacking context
that contains all the sticky contents. This ensures all those items pick

In particular, in nsCharClipDisplayItem::IsSelected() we know that
the frame must be a nsTextFrame (or nsContinuingTextFrame) which
means nsTextFrame::IsFrameSelected() can be called directly now.
This fixes the assertion, though not the test-case, but now I can debug the
test-case and also land it as failing for now.
What was happening is that we had two ASRs (for the canvas and for the <body>),
and we were creating scroll data for the CompositorHitTestInfo of the <body>
(which obviously didn't have any ancestor transform) and for the
nsDisplayTransform in the backface for which HasPerspective returns true for,
but which already had an ancestor transform for the frame for which

Previously, WebRender was getting a rectangle for reference frames
and stacking contexts, and it had to carefully treat the origin of this rectange:
- by offseting all the items in a stacking context
- by negatively compensating the sticky frame scroll port according to the
parent reference frame origin
With this change, we stop providing any non-zero origins. Instead we accomplish
the same behavior using existing API primitives, such as reference frames:
1. when a stacking context has an origin, we push another reference frame for it
2. when computing the sticky frame scroll port, we take this origin into account
This slightly simplifies Gecko-WR API, but more importantly it would allow WR to
get rid of this logic (of handling origins), which in turn would allow to switch
the reference frames from push()/pop() model to just define(), like we do for
scroll/sticky frames already.
