Ports renderer/{generic,cell,row,link,State,Overlay,image,Thread}.zig:
- generic.rs builds GPU cell buffers from terminal RenderState each
frame: backgrounds, shaped text runs with glyph atlases and nerd font
constraints, all cursor styles, decorations via sprites, selection and
search colors, min-contrast, bold/faint/blink handling, preedit,
padding extension, background image, custom shader uniforms, link
hover underlines, scrollbar and health reporting.
- The renderer thread updates CPU-side state only and asks the host to
redraw; the app runtime calls draw_frame from the GLArea render signal
(the GL context lives on the GTK thread, as in Ghostty).
- ghostty_renderer::state::{State, SharedState} is the canonical shared
renderer state (termio's interim copy will switch to it).
Deviations: overlay uses a direct RGBA rasterizer instead of z2d; bg
images decode with png/jpeg-decoder instead of wuffs; zero-length link
matches advance by one char (Zig would loop forever).
Kitty image rendering is implemented in image::State but not yet called
from generic::update_kitty (raced with the terminal-side wiring).
Test Plan:
- cargo test -p ghostty-renderer (69 unit + 9 headless EGL tests that
render a Terminal through the full pipeline and check pixels)
