We do not currently support bitmap fonts in a real capacity, and they
often are missing some tables which we currently rely on for metrics,
and we don't handle the metrics calculations failing gracefully right
now.
Annotate the node count of all uses of z2d `StaticPath` to verify
correctness, adjusted the size of a couple which were oversized, and
changed all painter calls that take node slices from `StaticPath`s to
use the slice from the wrapped `ArrayList` so that we don't include any
potentially `undefined` nodes at the end of the list, which I think was
causing a crash before.
Introduces static path methods and a reworked context API that makes
things generally cleaner.
This update incidentally fixed a bug we had before where the corner
triangle shade characters were drawn solid rather than medium shade.
Subsumes #2580 (which has multiple conflicts with main due to recent
changes to metrics); I figured it'd be easier to just implement it this
way.
#2580 claimed to solve #2487 but I don't think it really does- ideally
we can think of a good way to configure each individual cursor type, but
I don't wanna just do something ad hoc and add a bunch of config keys
blindly so I limited the scope of this.
Unicode 16 added "Separated Block Quadrants" from CP 0x0x1CC21 through
0x1CC2F:
To test, use the following command:
```
printf "\U0001CC21\U0001CC22\U0001CC23\U0001CC24\U0001CC25\U0001CC26\U0001CC27\U0001CC28\U0001CC29\U0001CC2A\U0001CC2B\U0001CC2C\U0001CC2D\U0001CC2E\U0001CC2F\n"
```
Which should look like this:

- Simplifies and clarifies the math for how the bounding box for
rendered glyphs is computed
- Reduces margin from 2px between glyphs to 1px by only padding the
bottom and right side of each glyph
- Avoids excessive padding to glyph box when font thicken is enabled or
when using a synthetic bold (it was previously 4x as much padding as
necessary in some cases)
Variable font init used to just select the first available predefined
instance, if there were any, which is often not desirable- using
createFontDescriptorFromData instead of createFontDescritorsFromData
ensures that the default variation config is selected. In the future we
should probably allow selection of predefined instances, but for now
this is the correct behavior.
I found this bug when adding the metrics calculation test case for
CoreText, hence why fixing it is part of the same commit.
Unify grid metrics calculations by relying on shared logic mostly based
on values directly from the font tables, this deduplicates a lot of code
and gives us more control over how we interpret various metrics.
Also separate metrics for underlined, strikethrough, and overline
thickness and position, and box drawing thickness, so that they can
individually be adjusted as the user desires.
addresses #2561 - adds support for most Git branch drawing characters as
specified in 
except for fading vertical and horizontal lines.
Adds git_draw_node function and a new Git node type.
Add this range (0xf5d0...0xf60d) for Git branch characters, to tests.
adds vline_middle_xy and hline_middle_xy for node connections.
add git characters to Face.zig.
This was causing discovery to find some odd fonts under certain
scenarios (namely: Recursive Mono). Due to our prior fix in
e08eeb2b2ad810c4db22530a181858caee834b22 we no longer need to set
variations here for them to stick.
This fixes an issue where for the regular style we were picking a
suboptimal style because for some font faces we were choosing more bold
faces (just as chance). This modifies our scoring to take the style
length into account even for regular style. We already had this logic
for explicit styles.
This commit makes CoreText behave a lot like FreeType where we set the
variation axes on the deferred face load. This fixes a bug where the
`slnt` variation axis could not be set with CoreText with the Monaspace
Argon Variable font.
This was a bug found in Discord. Specifically, with the Monaspace Argon
Variable font, the `slnt` variation axis could not be set with CoreText.
I'm not sure _exactly_ what causes this but I suspect it has to do with
the `slnt` axis being a negative value. I'm not sure if this is a bug
with CoreText or not.
What was happening was that with CoreText, we set the variation axes
during discovery and expect them to be preserved in the resulting
discovered faces. That seems to be true with the `wght` axis but not the
`slnt` axis for whatever reason.
