Cleaner and less visual noise, easy change to make, there are many other
areas in the code which would benefit from decl literals as well, but
this is an area that benefits a lot from them and is self-contained.
This sets the stage for dynamically adjusting the sizes of fallback
fonts based on the primary font's face metrics. It also removes a lot of
unnecessary work when loading fallback fonts, since we only actually use
the metrics based on the parimary font.
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.
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.
- Make canvas geometry primitives generic, use `Rect(u32)` for `rect`
function, so that we don't have to worry about negatives or rounding.
- Make `Quads` struct packed just in case it gets non-comptime use in
the future.
- Clarify comment on why we're discarding out of range pixels + runtime
unreachable for any other type of error which we shouldn't ever see.
- Move z2d import above in-tree imports.
More complete coverage of the Symbols For Legacy Computing block,
including characters from Unicode 16.0.
Pixman and the web canvas impl for Canvas have been removed in favor of
z2d for drawing, since it has a nicer API with more powerful methods,
and is in Zig with no specific platform optimizations so should compile
to wasm no problem.
Use a single unified function for intersection-style line drawing chars,
and one for fractional block characters. Add a ground truth image based
on this commit for the regression test (differences from before changes
validated visually, 1 incorrect rendering actually fixed)
- Limit max amplitude relative to cell width to avoid being too wavy
- Fix application of xiaolin-wu's for anti-aliasing too always be at
least 1px thick.
- Fix height calculation to avoid clipping bottom of wave at small
sizes.
