Linear gradient painting is implemented in the following way:
1. The rectangle is divided into segments where each segment represents
a simple linear gradient between an adjacent pair of stops.
2. Each quad is filled separately using a fragment shader that
interpolates between two colors.
For now `angle` and `repeat_length` parameters are ignored.
When a box does not have a top, left, bottom, or right, there is no
need to adjust the offset for positioning relative to the padding edge,
because the box remains in the normal flow.
The condition for checking if a script has a JS MIME type is currently
flipped. Extract the check to a local to make it a bit easier to reason
about at quick glance.
We now create a WorkerAgent for the parent context, which is currently
only a Window. Note that Workers can have Workers per the spec.
The WorkerAgent spawns a WebWorker process to hold the actual
script execution of the Worker. This is modeled with the
DedicatedWorkerHost object in the WebWorker process.
A start_dedicated_worker IPC method in the WebWorker IPC creates the
WorkerHost object. Future different worker types may use different IPC
messages to create their WorkerHost instance.
This implementation cannot yet postMessage between the parent and the
child processes.

This is a hack on top of a hack because Workers don't *really* need to
have a Web::Page at all, but the ResourceLoader infra that should be
going away soon ™️ is not quite ready to axe that requirement for
cookies.
We don't have a 'root execution environment' anymore (thankfully), so
we can make sure that the ESO the HostDefined object holds onto is a
NonnullGCPtr.
By using available_inner_space_or_constraints_from(available_space), we
ensure that the available space used to calculate the min/max content
height is constrained by the width specified for the box itself
(I know that at least GFC always expects available width to be
constrained by specified width if there is any).
This change improves layout in "Recent news" block on

This commit correctly validates the `type` and `subtype` arguments,
instead of checking for http quoted code points, by following how
the spec's MIME type parsing algorithm would validate a MIME type's
type and subtype.
It also uses the move-assigned member variables instead of the
arguments within the constructor body (as using the arguments at
this point will lead to undesired behavior).
The elements this hack was being used for were grouping elements, and
can be properly sized: https://svgwg.org/svg2-draft/struct.html#Groups.
Note: Other than one test change the elements here are already covered
by layout tests.
Since we already call `Painter::flush()` in `PageHost::paint()` we do
not need to do that again in `PaintingCommandExecutorGPU` destructor.
This makes GPU painting run noticeably faster because `flush()` does
expensive `glReadPixels()` call.
Audio loaders currently always output two channels, even if they were
encoded as mono. Therefore, we have to hardcode the channel count in
our audio plugin to avoid crashing until we can handle mono or multi-
channel audio better.
Fixes#21898
This only tracks whether the relevant steps should be executed at some
future (but very soon) time. This time will eventually be whenever the
"update animations and send events" procedure is invoked.
Framebuffer object is allocated using OpenGL's API and is not platform
specific which means it could be used on both macOS and Linux unlike
EGL specific PBuffer.
This is mostly a copy-paste of the algorithms already in StyleComputer
with spec links and comments. The only thing that really changed is the
handling of values outside of the range [0, 1] in the cubic bezier
function.
The implementation in StyleComputer will be removed in a later commit.
Some DOM APIs are restricted to user-activated events. For example, you
can't just invoke `navigator.clipboard.writeText` from JS - it has to be
accompanied by a user gesture, such as a mouse-down event. This adds an
Internals API to simulate such a gesture.
As far as I can tell all of these steps are just equivalent to using the
qualified name. Add some tests which cover some of these cases, and
remove the FIXME's.
