DeprecatedFlyString relies heavily on DeprecatedString's StringImpl, so
let's rename it to A) match the name of DeprecatedString, B) write a new
FlyString class that is tied to String.
Gfx::Color is always 4 bytes (it's just a wrapper over u32) it's less
work just to pass the color directly.
This also updates IPCCompiler to prevent from generating
Gfx::Color const &, which makes replacement easier.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This patch changes the initialization of the fill_color of an SVGContext
to transparent instead of black to not draw a black filling if the
elements fill_color is defined as "none".
Because the result will be a float anyway get rid of the int parsing.
Also the grammar of SVG numbers matches the double parser grammar except
it can't have a sign but that should have been checked by the caller.
This removes a set of complex reference cycles between DOM, layout tree
and browsing context.
It also makes lifetimes much easier to reason about, as the DOM and
layout trees are now free to keep each other alive.
The intent is to use these to autogenerate prototype declarations for
Window and WorkerGlobalScope classes.
And the spec links are just nice to have :^)
Unlike ensure_web_prototype<T>(), the cached version doesn't require the
prototype type to be fully formed, so we can use it without including
the FooPrototype.h header. It's also a bit less verbose. :^)
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.
There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Instead of using Optional<LengthPercentage>, we now use LengthPercentage
for these values. The initial values are all `auto`.
This avoids having to check `has_value()` in a ton of places.
The goal here is to move the parser-internal classes into this namespace
so they can have more convenient names without causing collisions. The
Parser itself won't collide, and would be more convenient to just
remain `CSS::Parser`, but having a namespace and a class with the same
name makes C++ unhappy.
This element doesn't actually support anything at the moment, but it
still massively speeds up painting performance on Wikipedia! :^)
How? Because we no longer paint SVG <path> elements found inside
<clipPath> elements. SVGClipPathElement::create_layout_node() returns
nullptr which stops the layout tree builder from recursing further into
the subtree, and so the <path> element never gets a layout or paint box.
Mousing over Wikipedia now barely break 50% CPU usage on my machine :^)
Percentage stroke widths are resolved against the scaled viewport size
which we were retrieving by calling client_width() and client_height()
on the element. Now that those accessors may trigger layout, this means
that we can't use them from the stroke_width() getter, which is itself
used *from within* layout.
This might not be entirely correct, but neither was using the completely
ad-hoc parse_html_length(), and this is the last user of that API so
let's move off of it.
There are a few unimplemented features for this type:
1. The value setter should throw a DOMException if it is invoked on an
SVGLength that was declared readonly in another IDL file.
2. SVG::AttributeParser does not parse unit types when it parses lengths
so all SVGLength will have an "unknown" unit for now.
3. Due to (2), methods which convert between units are unimplemented.
We were calculating the reflected control points in the svg smooth
curve instructions incorrectly, and this issue was masked by the fact
that we were treating it as a relative coordinate in relative mode.
