refactor(map): implement trait-based render graph (Phase 3)
- Define RenderPass trait with execute(), z_order(), zoom gating
- Implement 5 concrete passes: Background, Fill, Stroke, Poi, Label
- Create RenderContext to pass state to passes
- Refactor view.rs draw_walk() to use render_graph.execute()
- Reduce draw_walk() from 153 lines to 50 lines (-67%)
- Remove all hardcoded if-statements for pass execution
- Add 13 integration tests for render graph
- Enable true extensibility: new passes require only trait implementation
Benefits:
- Extensible: add custom passes without modifying view.rs
- Maintainable: each pass is self-contained
- Testable: passes can be tested independently
- Clean: view.rs reduced by 150 lines
Architecture:
NigigMapView.draw_walk()
-> creates RenderContext
-> render_graph.execute(&mut ctx)
-> iterates passes in z_order
-> calls pass.execute(ctx) for each enabled pass
This completes Phase 3 of the Makepad codebase improvement plan.
