Description
Summary
The visual-testing branch has a testing framework but several areas
lack test coverage. I'd like to add visual regression tests for:
- Primitive shapes (rect, ellipse, triangle, arc, line, point)
- Blend modes (OVERLAY, HARD_LIGHT, SOFT_LIGHT)
- Stroke styles (weight, cap, join)
- Transform operations (translate, rotate, scale)
Approach
Each area would be a separate focused PR.

Start by inspecting the visual-testing branch's existing testing framework and PR #1460. Add focused visual regression coverage for the listed primitives, blend modes, stroke styles, and transform operations, with each area handled as a separate PR, then verify the tests pass.
