The AsyncScreenshotGrabber now can operate in two modes:
* `ProfilerScreenshots`, which does asynchronous scaling of the captured frames
for inclusion in profiles by the Gecko Profiler; and
* `CompositionRecorder`, which does not do any scaling and is used for visual
metrics computations.
The latter mode is exposed by on the `Renderer` via the `record_frame`,
`map_recorded_frame`, and `release_composition_recorder_structures` methods.
A different handle type (`RecordedFrameHandle`) is returned and consumed by
these functions, but they translate between `RecordedFrameHandle` and
`AsyncScreenshotHandle` when communicating with the underlying
`AsyncScreenshotGrabber`.
I considered making the `AsyncScreenshotGrabber` generic over its handle type,
but the extra cost of monomorphization just to change the handle type did not
seem worth it.

When a blob image invalidates, it doesn't always repaint the entire
blob. When we stored the shared surface references in the DIGroup, it
would incorrectly forgot about images referenced by items that were not
invalidated when it repainted. As such, it could free them too early and
cause a crash when rasterizing the blob in the compositor process.
This did not crash most of the time because the image cache would bail
us out. It takes a full minute for the image cache to expire, but the
issue was more readily reproducible when that timeout was shortened.
We now store the references in BlobItemData, on a per display item
basis. This ensures that when any given item is invalidated, it will
continue referencing any resources that it needs.

By default, recycling frames for animated images is enabled. However the
first frame is never recycled because we may need the first frame
immediately if the animation is reset. If only the first frame of an
animation is displayed before shutting down a tab, then it will not
correctly register with the layer state manager prior to its
destruction. This trips an assert incorrectly.
Now we just always register with the layer state manager if recycling is

from state information at the cost of requiring a restart to toggle to

During the visibility pass, the main clip chain instance for each
primitive is created. In the prim prepare pass, a clip chain instance
is generated for each segment (of primitives that are segmented).
This previously required maintaining the active clip chain stack
during both passes. However, this is not ideal for a number of
reasons: the code is somewhat complicated / error prone and the
segment clip chain building step does more work than required.
This patch changes the segment clip chain building code to set up
the active clip nodes based on the result of the initial clip
chain built for the overall primitive during the visibility pass.
This means that it's no longer necessary to maintain the active
clip chain stack during the prepare pass. This simplifies some
upcoming picture caching changes related to avoiding redundant
cache invalidations, which is the main motivation for the change.

Previously, I changed changed the space mapper logic to use the world transformations.
This was seemingly needed because we requrested the relation between primitives and

However, I believe the change was a mistake, since for clips we should not even try
to get the relative mapping, and clipping is done in world space for these cases.
This change reverts that logic back. ~~Fingers crossed for the try to not show any

When pinch zooming webrender would re-rasterize glyphs for each tiny
difference in zoom level. This takes time in itself, but also causes
the texture cache to grow incredibly large, to the point where
resizing it to make room for more glyphs takes far too much time.
This patch avoids this by rounding the size at which glyphs are
rasterized whilst pinch zooming. To do this we add a FrameMsg which
APZ uses to tell webrender whether a spatial node is being pinch
zoomed. Then during frame building if a spatial node is being pinch
zoomed we override the raster space of its corresponding picture.
The chosen raster space is the current zoom level rounded up to the
nearest power of two, but not exceeding 8x. This seems to be a good
balance between quality and performance, though at high zoom levels
the cache still does grow very large due to the size of the glyphs.

In bug 1527182 we made it so that APZ can directly drag-scroll scrollframes
that are inside SVG effects, because that's possible with WR on the compositor.
However the code changed in that bug was meant to be kept in sync with
a second piece of code. The second piece of code controls the generation
of ScrollInfo items for scrollframes inside SVG effects - since we can
APZ-scroll them with WR, we don't need the scrollinfo item anymore.
Producing the scrollinfo item was changing the structure of the APZ tree
in terms of where the transform ended up, and was causing badness with
untransforming the drag mouse events.
This patch adds a test that covers the scenario and also corrects the defect
by bringing the two bits of code back in sync.

To fix bug 1496540 it was made so that webrender clips border corner
segments so that they do not overlap with their opposing
edges. However, cases where opposing _edges_ both overlap with
eachother (rather than just a corner overlapping with an edge), the
corners are clipped too far and a gap is left in the middle.
Additionally, no clipping was added to the edge segments. So rather
than there be a gap there is an area that is painted twice, which is
apparent if the colour is semi-transparent.
This fixes these issues by identifying when opposing edges overlap and
calculating the midpoint, then clipping the edges and corners to that
midpoint instead.
