GeckoView is still using the deleted gl.msaa-level setting. As the rest of the engine does not use it,
modifying it basically became a noop. Replacing it by webgl.msaa-samples does the trick and allows
GeckoView clients to modify the antialiasing settings in WebGL.

Bug 1766131 added a call to this method before the other call
to ReplacedBy, but apparently the other call site comes into play
in some tests, at least when parent controlled navigation is
enabled. This fixes browser_scrollPositions.js with parent controlled
navigation, and is a step towards fixing browser_test_shentry_wireframe.js.

It sounds like the issue happens when you navigate to one page, then
to another in the same site, via BrowserTestUtils. Because these are
initiated from the parent process, then end up getting redirected to
the content process in another docshell. We have to save the layout
history state before doing this, or we lose the scroll information.

This patch adds a edge aa mask field in the common primitive data so that primitives can turn off anti-aliasing at their edges. There was some padding in the structure so it didn't change the size.
This will be use by a followup patch to turn off anti-aliasing between pieces of linear gradients when they are decomposed into simpler primitives.

Bug 1726388 - Make it possible to not anti-alias at the bounds of the primitive. r=gfx-reviewers,lsalzman

The Antialiasing code sets up the bounds of a rect to anti-alias in the vertex shader for the fragment shader to compute the AA via a distance approximation.
The modified mix call selects between the edges of the current instance (could be a primitive segment) and the edges of the primitive based on the anti-aliasing edge flags. If an edge does not have the AA flag, then the aa will be computed based on the distance to the primitive's edge. This usually works because we tend to want AA around the primitive but not along the internal edges of potential segments of a primitive. However it also means that if we take the anti-aliasing code path (for example under a non-axis-aligned transform) then the edges of the primitive are always anti-aliased. In some cases we want to disable the anti-aliasing along the primtive, though, for example when something is split into multiple primitive like the linear gradient optimization.

This patch changes this mix call so that it selects between the segment bounds and some very large rect. If the primitive is not segmented, then the segment bounds are the bounds of the primitive. The effect is that AA is only applied to edges that have the flag set rather than segment edges with the flag set as well as any edge at the border of the primitive.

This instrumentation is used to build test cases and help with fuzzing, by
selecting a custom delazification type as the default mode for the top-level.

Differential Revision: https://phabricator.services.mozilla.com/D145993

Adds a delazification mode, which spawn a concurrent depth-first delazification
of all function to fill the stencil cache, to later compare cached results with
stencils produced by on-demand delazification.

The delazification mode also works when being used from a main-thread top-level
compilation, in which case the delazification tasks are created and potentially
blocking the main thread, while the delazification is happening.

This way of doing help comparing on-demand delazification, based on instantiated
stencils with concurrent delazification, based on stencils. Which is a good
mode for fuzzing purposes.

Differential Revision: https://phabricator.services.mozilla.com/D145992

Previously, we only had a single mode of delazification, then we added the
concurrent delazification, which could be mixed with on-demand delazification,
by always checking for cached entries.

Now, with the addition of a third mode which attempt to compare the outputs of
on-demand delazification with concurrent delazification, we need to distinguish
and carry this difference to the function responsible for running the
delazification. However, this information is only available when we first run
the delazification.

This patch adds the JS::DelazificationOption (uint8_t) to the ScriptSource
class, such that we can communicate the selected mode to the functions in charge
of the delazification.
