Detailed Description

Frozen baseline for the Metal solid-fill vertical slice

solid_fill_baseline.png is the design 0053 phase 3 frozen baseline: the shared baseline scene (donner/gpu/metal/tests/BaselineScene.h - a translucent red quadratic-segment circle (non-zero), a self-intersecting blue star (even-odd), and an opaque green cubic blob overlapping both) rendered at 256x256 RGBA8 over a transparent background.

It was captured from the current production renderer as a black box - the wgpu-based Geode path running on the Metal backend of an Apple Silicon Mac - using:

bazel run --config=geode //donner/gpu/metal/tests:baseline_capture_tool -- \
  $(bazel info workspace)/donner/gpu/metal/tests/testdata/solid_fill_baseline.png

metal_solid_fill_tests renders the identical scene through donner::gpu::metal::MetalDevice with the MSL emitted from the solid-fill IR program and compares pixels against this PNG with the blessed pixelmatch comparator. Regenerate only deliberately (an intentional change to the baseline scene or to the production renderer's output), rerun the capture command above on the target machine, and re-run the slice test.
