This Adds an element size preview widget to the inspector widget
in a new tab. This functions similar to chrome and firefox and
shows the margin, border, padding, and content size of the selected
element in the inspector.
The colors for the size preview widget are taken from the chrome
browser.
Note that we don't put absolutely positioned items on a line! This is
just so that IFC can discover boxes and pass them along to BFC.
This fixes an issue where only direct children of the IFC containing
block were considered for absolute positioning. Now we pick up
absolutely positioned children of nested inline nodes as well.
As noted, the Parser can't handle the `<number>` syntax for this - it
gets parsed instead by the `<number>` branch. We can't actually resolve
the ambiguity without making the Parser aware of what type each
media-feature is, but I will get to that soon. :^)
This patch adds support for "crisp-edges", "high-quality" and "smooth"
for the CSS image-rendering property.
"crisp-edges" maps to nearest-neighbor scaling for <canvas> and <img>
elements, while "high-quality" and "smooth" both use bilinear blending.
Previously, the decoration was painted behind the text. This probably
wasn't noticed before, as we didn't compute `text-decoration-color`
values yet and the decoration had the same color anyway.
Previosly, we used only the text color as a line decoration color.
The FIXME comment has been directly copy-pasted from the border color
note a few lines below.
The spec says "fire an event named resize at the Window object
associated with doc."
However, we were accidentally firing it at `doc` instead of the Window.
If the content wants to be pixelated, we should honor that and paint
with nearest-neighbor scaling. The fact that it's faster is a nice bonus
as well. :^)
- Perform a typed this check
- Use the 'associated URL' as the source of truth
- Don't append default port number in the host getter
- Don't return default port number in the port getter
- Add empty checks to the hash and search getters instead of returning
'#' and '?' strings from the string builder

This revealed a variety of issues, mostly missing origin checks,
conflating concepts like the 'associated URL', and serialization
(incorrect fallback values, string vs number, etc).
This commit fixes none of these issues, only adds FIXMEs.
When recomputing the style for an element that previously didn't have
a corresponding layout node, it may become necessary to create a layout
node for it.
However, we should not do this if it's within a subtree that can't have
layout children. Nor should we do it for elements who have an ancestor
with display:none.
Not sure why these are doubles in the IDL definition, both the IDL in
the spec and the implementation in the CanvasRenderingContext2D class
use integers.
Also add support for HTMLCanvasElement for the image parameter, leading
to replacing HTMLImageElement with the CanvasImageSource Variant type.
Also stub out the 'check the usability of the image argument' and 'is
not origin-clean' operations, while taking into consideration that these
can throw (and require DOM::ExceptionOr).
