https://github.com/vancluever/z2d/blob/v0.9.0/CHANGELOG.md
This release brings our Zig 0.15.x branch into main, now that Ghostty is
on it too.
Additionally, this adds major speedups to the default path (filling with a
solid color using the default operator).

This adds a new script we can manually run that downloads all the files
that need to be uploaded to the mirror and updates our build.zig.zon.
The upload still happens manually [by me] but this simplifies the task
greatly.

Since we now use uucode, we don't need ziglyph anymore. Ziglyph was kept
around as a test-only dep so we can verify matching but this is
complicating our Zig 0.15 upgrade because ziglyph doesn't support Zig
0.15. Let's just drop it.

There is an upstream bug where subsequent releases will nuke prior
released packages, resulting in 404s. Not good!

Small release again, just keeping up to date with releases in
anticipation of the Ghostty 1.2.0 release.

This is a small update and likely contains nothing related to Ghostty,
but I wanted to make sure it got in before the 1.2.0 release since it
contains the removal of non-functional code that wasn't compiling, just
for correctness' sake.
Also if for some reason ARGB/XRGB is needed for some utility purpose,
it's there now. :)

Release notes at:
https://github.com/vancluever/z2d/blob/v0.7.2/CHANGELOG.md
This is mostly a bugfix release for text rendering, including a fix for
an invalid free flagged as:
https://github.com/vancluever/z2d/security/advisories/GHSA-v7f4-f3hm-282w
Note that the invalid free affects the new in-library text rendering
only and as such is likely not in use in Ghostty.
I'm anticipating *maybe* one more release after this ahead of Ghostty
1.2.0, depending on if I find any more bugs, but close to around the
release I am planning a freeze to ensure a clean versioned release
continues to be set.

This release contains performance and memory use improvements.
Some of the sprite font test renders had to be updated due to very minor
differences in the anti-aliasing, since the default anti-aliasing method
in z2d has been changed to MSAA rather than SSAA.

The upstream GIR for g_weak_ref_get is incorrect - it does not allow the
returned value to be NULL. This PR pulls in a new version of our GObject
bindings with that patched and improves the safety of dealing with the
command palette weak reference held by the window.

This drops our `usingnamespace` usage to one more library (zigimg via
libvaxis) which should get fixed soon. With that, we have zero
usingnamespace and we should be able to test incremental compilation
with Zig (no binary mode, so Sema only) amongst other future features.

This is a big'un.
- **Glyph constraint logic is now done fully on the CPU** at the
rasterization stage, so it only needs to be done once per glyph instead
of every frame. This also lets us eliminate padding between glyphs on
the atlas because we're doing nearest-neighbor sampling instead of
interpolating-- which ever so slightly increases our packing efficiency.
- **Special constraints for nerd font glyphs** are applied based roughly
on the constraints they use in their patcher. It's a simplification of
what they do, the largest difference being that they scale groups of
glyphs based on a shared bounding box so that they maintain relative
size to one another, but that would require loading all glyphs on the
group and I'd want to do that on font load TBH and at that point I'd
basically be re-implementing the nerd fonts patcher in Zig to patch
fonts at load time which is way beyond the scope I want to have. (Fixes
#7069)
- These constraints allow for **perfectly sized and centered emojis**,
this is very nice.
- **Changed the default embedded fonts** from 4 copies (regular, italic,
bold, bold italic) of a patched (and outdated) JetBrains Mono to a
single JetBrains Mono variable font and a single Nerd Fonts Symbols Only
font. This cuts the weight of those down from 9MB to 3MB!
- **FreeType's `renderGlyph` is significantly reworked**, and the new
code is, IMO, much cleaner- although there are probably some edge case
behavior differences I've introduced.
> [!NOTE]
> One breaking change I definitely introduced is changing the
`monochrome` freetype load flag config from its previous completely
backwards meaning to instead the correct one (I also changed the
default, so this won't affect any user who hasn't touched it, but users
who set the `monochrome` flag will find their fonts quite crispy after
this change because they will have no anti-aliasing anymore)
### Future work
Following this change I want to get to work on automatic font size
matching (a la CSS
[`font-size-adjust`](https://developer.mozilla.org/en-US/docs/Web/CSS/font-size-adjust)).
I set the stage for that quite some time ago so it shouldn't be too much
work and it will be a big benefit for users who regularly use multiple
writing systems and so have multiple fonts for them that aren't
necessarily size-compatible.
