2a3675f0c1 LibWeb: Make "currentcolor" lowercase in Properties.json 
It's technically case-insensitive, but the spec always defines it as
"currentcolor" so it feels wrong to capitalise it differently there.

854d6e5822 LibWeb: Persuade CSS Parser that idents like currentcolor are colors 
Shorthand properties were only checking for `ColorStyleValue`s, which
excludes identifier colors. Now they accept them too, including the
various `-libweb-foo` colors. :^)

17bb913625 LibWeb: Implement currentcolor special value 
The `currentcolor` identifier represents the current value of the
`color` property. This is the default value for `border-color` and
`text-decoration-color`, and is generally useful to have. :^)

86f78bff2a LibWeb: Make StyleValue::to_color() take a Node instead of the Document 
This is in preparation for the `currentcolor` value, which needs to know
what Node it's on so it can check the `color`.

c2c007b356 LibWeb: Don't request WebContent repaint while we have repaints pending 
This prevents flickering by ensuring that WebContent is only ever
painting into the back buffer bitmap. Without this change, it was
possible for WebContent to paint into the front buffer bitmap.

17a5c96b7c LibWeb: Make a SharedBitmap struct for OOPWV bitmaps 
Instead of having separate members for "bitmap ID" and "bitmap", let's
wrap them in a struct.

4fcb1be734 LibWeb: Skip rendering box-shadow blur if we don't have memory for it 
A slight loss in graphical fidelity is better than not rendering the
page at all.

64df30230d LibWeb: Add HTML::Task::Source::IdleTask 
This represents what the spec calls the "idle-task task source".

f8ea730f29 LibWeb: Flexbox: Add default value for AlignItems 
Previously there was no default value and wrapping broke when the
container didn't have a align-items specified.

3964b81d2b LibWeb: Add for CSS fill/stroke/stroke-color properties for SVG 
In the spec, `fill` and `stroke` are supposed to be a shorthands for
various properties. But since the spec is still a working draft, and
neither Firefox or Chrome support the `fill-color` or `stroke-color`
properties, we'll stick with `fill` and `stroke` as simple colors for
now.

Also, note that SVG expects things in "user units", and we are assuming
that 1px = 1 user unit for now.

2b57018196 LibWeb: Use default instead of an empty constructor/destructor 
Default implementations allow for more optimizations.

d69e4f9ca7 LibWeb: Don't dump full data URLs in ResourceLoader logging 
Some pages use *really* large data URLs. :^)

58b84f953c LibWeb: Add fast_is<HTMLTemplateElement>() 
This was showing up as hot in profiles, as the HTML parser calls it
quite a lot.

Auto is not specified at all.

6c15eeb367 LibWeb: Flexbox: Somewhat suppport "align-items" 
There probably are a lot of edge cases missing but this moves us forward
at least a bit.

307f90b675 LibWeb: Add proper parsing of the AlignItems property 
This teaches all the relevant places about 'align-items'.

422d725c79 LibWeb: Support "c" and "C" curves in SVG <path> data 
These instructions now generate cubic Bézier curves.

a269a32a17 Meta: Use Lagom:: namespaced names for code generators 
This will be required when we switch to a SuperBuild that has Lagom as
a configure time dependency, but is a distinct enough change to be
separate.

28fabd4728 LibWeb: Make Layout::Node::paint() pure virtual 
In the past, the base class implementation of this was used to descend
into subtrees and paint children. That is now taken care of by
StackingContext::paint_descendants() instead, and nothing used this.

eac31e21f2 LibWeb: Avoid some redundant calls to Layout::Box::absolute_rect() 
Computing the absolute rect of a box requires walking the chain of
containing blocks and apply any offsets encountered. This can be slow in
deeply nested box trees, so let's at least avoid doing it multiple times
when once is enough.

ee671a20cc LibWeb: Make flex-box ignore out-of-flow child boxes 
Previously, out-of-flow children still took up space inside a flex-box
container, leaving an odd gap. Now they don't! :^)

2844f89a83 LibWeb: Implement "out-of-flow" property of Layout Box 
In some situations, a layout box should not participate in the standard
layout process, for example when set to `position: absolute`.

7de23aede2 LibWeb: Parse the <svg viewBox> attribute 
Just parse it into an SVG::ViewBox object for now, we don't actually use
it for anything yet.

63c4fcdc69 LibWeb: Add SVG::ViewBox to represent SVG view boxes 
This also comes with a simple little parsing helper. :^)

8949b0def6 LibWeb: Add an SVG::AttributeNames namespace 
There are a whole bunch of SVG attributes, and we shouldn't mix them in
with the HTML attributes. This patch adds some of them to the new
namespace, but there are more to be added. :^)

3f31f109b5 LibWeb: Speed up computed style calculation 
Rather than destroying and rebuilding the entire document layout tree in
every call to `ComputedCSSStyleDeclaration::property()`, we now just
make sure that the layout tree exists.

This speeds up the DOM Inspector significantly, from taking several
seconds to select an element, to almost instant. :^)

tag during foreign content parsing.

fad825e94e LibWeb: Flexbox: Avoid division by zero 
This is not a good thing, one should not divide by zero! :^)

85af2ac450 LibWeb: Flexbox: Change the name of a variable to correspond to spec 
The spec used two different names for the same thing, and it was
confusing to read the spec on the one side and have the other name in
the code.

15b61ce143 LibWeb: Flexbox: Resolve relative size of flex-items more correctly 
This is still very much not the right thing to do, but at least
relatively sized flex-items get the right size.

047c013be0 LibWeb: Add several computed CSS styles 
These are mostly combined styles such as background, as well as handling
the Invalid and Custom property IDs (which both make no sense).

6865a5a447 LibWeb: Add CombinedBoderRadiusStyleValue for CSS border-radius 
This style value can hold all four border radii and format them into
valid CSS for the `border-radius` property.

20fb900937 LibJS+LibWeb: Move script parse time logging from JS::Script to LibWeb 
Let's only log HTML::ClassicScript parse times for now. Otherwise things
will get excessively noisy in test-js and the test262 runner.

Andreas Kling
10c489713d LibJS+LibWeb: Let JS::Script::parse() return a list of errors (on error) 
These are really supposed to be a list of SyntaxError objects, but for
now we simply return all the Parser::Error objects we got from Parser.

f62477c093 LibWeb: Implement HTML fragment serialisation and use it in innerHTML 
The previous implementation was about a half implementation and was
tied to Element::innerHTML. This separates it and puts it into
HTMLDocumentParser, as this is in the parsing section of the spec.

This provides a near finished HTML fragment serialisation algorithm,
bar namespaces in attributes and the `is` value.
