We don't need to notify the web views that some deeply nested iframe
has started loading a new URL (and we don't want it showing up in the
browser location bar either!)
Two issues made this class unusable on other platforms:
- Hardcoded /res paths to icons
- It required a GUI::TreeView for palette access
This patch simply patches out those features on non-Serenity systemsf
for now.
When mousing over twitter, 17% of time was spent computing stacking
context transform origins. Since this never changes after the stacking
context is created, we can cache it and avoid all that work.
Let's stop putting generic types and AOs from the Web IDL spec into
the Bindings namespace and directory in LibWeb, and instead follow our
usual naming rules of 'directory = namespace = spec name'. The IDL
namespace is already used by LibIDL, so Web::WebIDL seems like a good
choice.
These are from the HTML spec and therefore belong in the HTML/ directory
in LibWeb. Bindings/ has become a bit of a dumping ground, so this is a
first step towards cleaning that up.
63c727a was meant to stop clipping absolutely positioned descendants,
but used `is_positioned()` rather than `is_absolutely_positioned()`,
which meant it disabled clipping in many more cases that it should
have.
This fixes an issue where, when looping over the components of a
composite glyph, we used to mutate the affine transformation of the
glyph itself when computing the transformations of its components.
(AffineTransform::multiply() is non-const).
In case of possible framebuffer mapping overflow, just fallback to the
safe mode-setting of the DisplayConnector, because in that state we know
for sure that we can map a usable framebuffer (otherwise it is a bug in
the Kernel, and not WindowServer).
This value will be used later on by WindowServer to reject resolutions
that will request a mapping that will overflow the hardware framebuffer
max length.
We simply don't need that field anymore, as it was used when one
FramebufferDevice could contain multiple framebuffers within it, each
for a connected screen head.
This ends up having a big impact on performance, as we now correctly
treat a used flex-basis of `content` as `max-content` which means
we can use cacheable intrinsic sizes for flex items in the majority
of cases.
This was used by FFC to estimate the height of flex items after
performing layout inside them.
Now that we have automatic_content_height(), we no longer need this
awkward API and we can fold it into BFC's own height calculation.
Previously, this would overflow when both length and offset were
zero, leading to an OOB index into es_array_buffer. This would lead to
a crash on a few MDN pages.
This function should return the automatic height of the formatting
context's root box.
Until now, we've been relying on some magical handshakes between parent
and child context, when negotiating the height of child context root
boxes. This is a step towards something more reasonable.
SafeFunction automatically registers its closure memory area in a place
where the JS garbage collector can find it.
This means that you can capture JS::Value and arbitrary pointers into
the GC heap in closures, as long as you're using a SafeFunction, and the
GC will not zap those values!
There's probably some performance impact from this, and there's a lot of
things that could be nicer/smarter about it, but let's build something
that ensures safety first, and we can worry about performance later. :^)
