279924242d LibWeb: Add CSS CompositeStyleValue 
This represents the value of properties assigned via their shorthands,
and is expanded when computing actual property values.

e8a946c674 LibWeb: Remove StyleValue::has/to_length() 
Specifically, stop letting NumericStyleValues holding `0` from
pretending to hold a Length. The parser is now smart enough that we
don't have to do this. :^)

5cbf6eb930 LibWeb: Remove StyleValue::has/to_integer() 
Only NumericStyleValue holds integers.

I'm not sure our current distinction between NumericStyleValue holding
an integer or non-integer is useful given it always returns a float.
:thonk:

4ecf0b7768 LibWeb: Remove StyleValue::has/to_number() 
Only NumericStyleValue holds numbers.

Renamed `to_number()` to `number()` because it's just a getter now.

5f755d721e LibWeb: Remove StyleValue::has_rect() 
This behaves identically to `is_rect()`

f6fae315e3 LibWeb: Add CustomIdentStyleValue, along with parsing for it 
This corresponds to the `<custom-ident>` type in CSS grammar.

5533413061 LibWeb: Remove "Invalid" StyleValue type 
We never actually use this, we always initialize StyleValues with a
proper type.

be10360350 LibWeb: Move resolution of font weights and slopes to StyleValue 
This isn't exactly ideal factoring (though I'm not sure what is) but
this will make it possible to reuse this code in the parser.

31e1be0438 LibWeb: Support multi-keyword syntax for CSS display property 
The Display class already supported all specific values, and now they
will be parsed too. The display property now has a special type
DisplayStyleValue.

bebf4363db LibWeb: Change name of GridTrackSizeListStyleValue 
Change the name of GridTrackSizeStyleValue to
GridTrackSizeListStyleValue which is more accurate.

0679b4e0b9 LibWeb: Wrap font metrics into a struct 
Rather than passing an increasingly-unwieldy number of font parameters
individually to every function that resolves lengths, let's wrap them
up.

This is frustratingly close to being `Gfx::FontPixelMetrics`, but bitmap
fonts cause issues: We choose the closest font to what the CSS
requests, but that might have a wildly different size than what the
page expects, so we have to fudge the numbers.

No behaviour changes.

2fbe5b969b LibWeb: Add URLStyleValue to represent general url() values 
This is primarily being added to support `fill: url(#gradient)` for
SVGs.

f099ee3d47 LibWeb: Allow doing .to_color() on a StyleValue without a layout node 
This will be needed to access the color of a stop from a SVG gradient
<stop> element (which does not participate in layout, so does not have
a layout node).

0f9f6aef81 LibWeb: Simplify StyleValue API now that auto isn't a length 
Now that LengthStyleValue never contains `auto`, IdentifierStyleValue is
the only type that can hold an identifier. This lets us remove a couple
of virtual methods from StyleValue.

I've kept `has_auto()` and `to_identifier()` for convenience, but they
are now simple non-virtual methods.

2a659693bc LibWeb: Add EdgeStyleValue 
This represents a single edge and offset, this will be needed for
the values of background-position-x/y.

16e3a86393 LibWeb: Make absolutized_length() helper a Length method 
There were a mix of users between those who want to know if the Length
changed, and those that just want an absolute Length. So, we now have
two methods: Length::absolutize() returns an empty Optional if nothing
changed, and Length::absolutized() always returns a value.

7d29262b8b LibWeb: Move to_gfx_scaling_mode() helper

d64ddeaec4 LibWeb: Move PositionValue into its own files 
It's in Position.{h,cpp} because it represents a <position> in CSS, even
though it's currently named PositionValue to avoid collisions.

bcebca62d3 LibWeb: Move CSS::EdgeRect into its own files 
Also remove the unused StyleValue::to_rect() because an EdgeRect is only
ever held by a RectStyleValue.

b3a7a00ccf LibWeb: Move BackgroundSize enum to ComputedValues.h 
Again, this doesn't belong in StyleValue.h, though this may not be the
ideal place for it either.

c4afa79fed LibWeb: Move FlexBasis enum to ComputedValues.h

7a1a97f153 LibWeb: Remove CalculatedStyleValue from Angle 
...and replace it with AngleOrCalculated.

This has the nice bonus effect of actually handling `calc()` for angles
in a transform function. :^) (Previously we just would have asserted.)
