This makes the WebGL2 implementation file inherit from the WebGL1
implementation file. This is actually closer to what the IDL files
describe and allows us to not have to maintain two copies of the same
functions.
The reasoning behind this is that in the next commit some of the WebGL2
specific parameters will be moved here. This header is needed to give
us access to those defines. Note that when in WebGL1 nothing from ES3
will be used as it's locked behind WebGL2 checks (it wouldn't work
anyways as we request ES2 from ANGLE).
This is more like what the IDL files specify with two different mixins,
but the inheritance structure here is slightly different for easier
maintenance. This will also allow the WebGL2 Impl to inherit from the
WebGL1 Impl as WebGL versions don't share the functions defined in the
Overloads interfaces.
Makes the `compute_font_variation_settings` function match other
`compute_font_*` by absolutizing values passed into them. It resolves a
crash related to using `siblings-count` inside `font-variation-settings`

Integrates the new `FontVariationSettings` from LibGfx into LibWeb to
enable initial variable font functionality. Currently, only the `wght`
(weight) axis is fully supported and tested. This update also introduces
support for the CSS `font-variation-settings` property.
This algorithm is used by Typed-OM for producing a list of internal
style values from a single one, for properties that take a list. We
will probably need to implement this for more StyleValues later.
Now that we don't remove whitespace when parsing, we don't need to
artificially insert it back in again when serializing. We do now need
to trim leading and trailing whitespace from UnresolvedStyleValues, as
this previously was done as part of the whitespace insertion.
This makes our serialization of UnresolvedStyleValues more correct and
gets us a few WPT passes for each property in the Typed OM tests.
Now that we don't strip out whitespace, this method was copying the
input TokenStream into a Vector, and then creating new TokenStreams
from that. So, stop doing that and use the input TokenStream instead.
