This allows calling code to specify whether a primitive would prefer
to be promoted to a compositor surface and/or picture cache slice.
This is a performance hint that can be used for large external
primitives, such as videos and canvas elements.

There are a number of issues with the current gradient dithering
implementation, that cause many test failures and also fuzziness
rendering when enabling DirectComposition virtual surfaces. In
particular, the dither result is dependent on the offset of the
update rect within a render target.
For now, this patch disables gradient dithering by default. This
gives us:
- A heap of new test PASS results (or reduced fuzziness).
- Fixes a number of non-deterministic fuzziness bugs with DC.
- Improves performance of gradient rendering by a reasonable amount.
We can fix gradient dithering as a follow up, and re-enable if/when
we find content that would benefit from it significantly (we may
be able to improve gradients in other ways than dithering too).

The semantics of the inaccuracy reftest mode are that the overall
test succeeds as long as one of the multiple test images mismatches
the reference image.
However, the previous implementation would print an unexpected result
if any of the comparisons were equal (even though the overall test
result would be reported correctly).
This patch changes wrench so that it only reports an unexpected
failure for the overall test, not each individual reference.

Unlike other types of render tasks, pictures can have hundreds of dependencies. The dependency vector is re-built every frame, leading to a lot of vector re-allocations in some pages.

The majority of render tasks have 0, 1 or 2 dependencies, except for pictures that typically have dozens to hundreds of dependencies. SmallVec with 2 inline elements avoids many tiny heap allocations in pages with a lot of text shadows and other types of render tasks.

This patch introduces a new reftest (syntax ** or !* in reftest files).
This type of test renders a single input file multiple times, at a range
of different picture cache tile sizes. It then verifies that each of the
images matches (or doesn't).
This can be used to verify rasterizer accuracy when drawing primitives
with different tile sizes and/or dirty rect update strategies.
One of the included tests in this patch fails the accuracy test - the
intent is to fix this inaccuracy in a follow up patch and then be able to
mark it pixel exact.

Optionally serialize N frames into a circular memory buffer, and save
them as part of wr-capture into tilecache/.
The new tile_view utility reads the folder and converts the frames to
svg for easier visualization, with a few extra features:
- color code each primitive based on which slice it is on;
- highlight new or moving primitives in red (brute force diff);
- print all invalidated tiles at the top and the invalidation reason;
- overlay the tile quadtree to visualize splitting & merging;
- HTML and JS wrappers for animation playback, timeline scrubbing;
Positioning of the tiles on the screen is a bit broken still; especially
during scrolling and "special" pages (like about:config).
Interning info is not used yet.

I removed the old opacity filter path in the brush_blend shader and cleaned up the filter mode
constants in the shader so there are less magic numbers. This should help if/when we move more
filters to their own shaders.

Opacity is a common effect that is used and the opacit filter path is also used when a stacking
context has an opacity of < 1. The brush_blend shader is slow since it has support for a large
portion of CSS filters; however, opacity is used much more often than the rest of the filters.
This patch adds a simple shader for opacity effects which bypasses the extra overhead in the
brush_blend shader.

This adds support for holes within virtual surfaces. On platforms
that don't use virtual surfaces, this just works by destroying

Adds an #ifdef to the DCLayerTree implementation that allows
selecting whether to use the virtual surface API (enabled by
default) or the regular DC surface API.
For now, this is a compile-time switch. As a follow up to this,
we will support both options at runtime (for example, using the
regular surface API for surfaces that have holes or translucency).

This will allow use of the DirectComposition virtual surface API. If
it turns out that some pages recreate surfaces a lot due to opacity
changing, we can add some extra logic to avoid recreating surfaces
as often, and making use of per-tile opacity in some cases.
