This patch updates the flake to track the nixos-unstable branch instead
of master for the nixpkgs flake input.
This ensures that hydra.nixos.org (the NixOS CI) has built all packages,
made them available in the cache.nixos.org binary cache without the risk
of a definitions (evalulation) being broken on master.
If one profile uses PCSXYZ and the other PCSLAB as connection space,
we now do the necessary XYZ/LAB conversion.
With this and the previous commits, we can now convert from profiles
that use PCSLAB with mAB, such as stress.jpeg from
https://littlecms.com/blog/2020/09/09/browser-check/ :
% Build/lagom/icc --name sRGB --reencode-to serenity-sRGB.icc
% Build/lagom/bin/image -o out.png \
--convert-to-color-profile serenity-sRGB.icc \
~/src/jpegfiles/stress.jpeg
ICC profiles work by transforming from the input color space
(one of many: RGB, CMYK, YUV, etc) to a "profile connection space" (PCS)
and then from there to the output color space.
However, there's not one but two possible profile connection spaces,
PCSXYZ and PCSLAB. The matrix/curve tags can only be used with PCSXYZ,
but the mAB, mBA, mft1, mft2 tags can be used with PCSLAB as well.
The PCSLAB encoding has L going from 0 to 100 and ab from -128 to 127,
instead of from 0 to 1. So they need to be scaled up at the end.
That's also the reason for the "mystery conversion factor": PCSXYZ
doesn't go from 0 to 1 either, but from 0 to 65535/32768, per ICC v4
6.3.4.2 General PCS encoding, Table 11 - PCSXYZ X, Y or Z encoding.
Between input and output are various curves (and the CLUT) that
have domain and range of 0..1. For these, the color has to be linearly
scaled to 0..1 before the curve and back to the actual range after
the curve. Doing that back-to-back is a no-op, so scaling back at
the very end is sufficient.
We will need to use ColorSpace in TagTypes.h, and it can't include
Profile.h.
Also makes Profile.cpp a bit smaller.
No behavior change, pure code move.
This allows a limited amount of DOM manipulation through the Inspector.
Users may edit node tag names, text content, and attributes. To initiate
an edit, double-click the tag/text/attribute of interest.
To remove an attribute, begin editing the attribute and remove all of
its text. To add an attribute, begin editing an existing attribute and
add the new attribute's text before or after the existing attribute's
text. This isn't going to be the final UX, but works for now just as a
consequence of how attribute changes are implemented. A future patch
will add more explicit add/delete actions.
This adds APIs to allow Ispector clients to:
* Change a DOM text or comment node's text data.
* Add, replace, or remove a DOM element's attribute.
* Change a DOM element's tag.
After commit ff48b7333c, we remove shadow
roots from elements that are removed from the DOM. Setting a node's
shadow root to null also sets that shadow root's host to null. Thus, the
comment in Node::is_shadow_including_descendant_of that assumes the host
is always non-null is not true.
The test added here would previously crash when interacting with a node
that is a descendant of a removed shadow root.
Previously we would calculate the index of the first parent node as
heap.size() (which is initialized to non_zero_freqs), so in the edge
case in which all symbols had a non-zero frequency, we would use the
Size-index entry in the array for both the first symbol's leaf node,
and the first parent node.
The result would either be a non-optimal huffman code (bad), or an
illegal huffman code that would then go on to crash due to an error
check in CanonicalCode::from_bytes. (worse)
We now store parent nodes starting at heap.size() - 1, which eliminates
the potential overlap, and resolves the issue.
I'm not entirely sure why this is needed, but it's the same ol'
workaround we're using in a bazillion places where we get caught trying
to do JavaScripty things without a running execution context.
This ensures that repeated loads of the same module succeed. (There is a
specific criteria where the same exact module object has to be returned
for multiple loads of the same referrer + specifier.)
Note that we don't check the referrer at the moment, that's a FIXME.
In particular, this patch focuses on:
- Updating the old "import assertions" to the new "import attributes"
- Allowing realms as module import referrer
This allows them to participate in the ownership graph and fixes a
lifetime issue in module loading found by ASAN.

This fixes an issue where we end up in a state where we have no
execution context + a main thread event loop with an empty incumbent
settings object stack.
