Check Document::hidden() in LayoutObject::WillRenderImage,
thus pausing animations on pages that are not visible.
To resume animations, we may need to explicitly resume the
timeline, so a hook is added in Page::SetVisibilityState to
allow calling StartAnimation() on the relevant SVGImages.

Managing the Surface/SurfaceTexture pair is somewhat expensive,
and we don't need it for SharedBuffer transport. Now that the
mailbox_to_surface_bridge supports surfaceless initialization
(thanks to AR mode), use that to avoid this allocation.

This required some minor reshuffling to ensure we have the
right initialization order.

This change applies three heuristics to make trackpad scrolling feel
smoother. We increase the frequency at which we submit scroll events to
the platform, we also decrease the scroll scale factor (to make the
scrolls less jumpy), and we do some simple filtering of our scroll
values.

I pair-programmed much of this change with asimjour@ and he wrote the
initial code to interpolate events in the android ui gesture target.

This patch corrects most of the known issues we have with sprite use
in background images under zoom, cracks at the border of background
images, failing to fill the positioning area with round, cover and
space, etc. There may still be cases we fail at but they do not appear
in bug reports or they are significantly harder to fix (meaning
requiring changes in Skia or elsewhere).

The primary change is to track snapped and unsnapped values throughout
the background rendering pipleline, and use the appropriate values
for every calculation. In general, this means using unsnapped values
when trying to compute something related to source pixels, and snapped
values when trying to describe the region for painting or calculations
intended to interact with the destination region.

There is scope for simplifying the code but they can wait until this
has landed and stuck. In particular, we add and then subtract offsets
when determinine source rects. And we do some odd adjustments for
certain scrolling cases that seem like they could be removed.

New tests cover various sprite sampling under zoom conditions.
Several ref tests had to be converted to image tests because repeated
images are now sub-pixel sized and cannot easily be matched with a
reference result.

It's simpler and more direct.
