Expand test coverage from ~19% to ~25% of GAL API with modular scenario files:
- bezier-curves: Tests DrawCurve() with S-curves, waves, hearts, and control points
- arc-segments: Tests DrawArcSegment() with thick arc strokes (PCB trace style)
- segment-chain: Tests DrawSegmentChain() with zigzags, spirals, sharp corners
- group-caching: Tests BeginGroup/EndGroup/DrawGroup for cached geometry
Architecture:
- New scenarios in separate files under scenarios/
- Forward declarations in main gal_test_scenarios.cpp
- CMakeLists.txt updated to compile new scenario modules
Also:
- Remove unused build-wxwidgets-native.sh (using system wxWidgets)

Add a standalone test application that compiles KiCad's actual OPENGL_GAL
against system wxWidgets to generate baseline screenshots for comparing
native OpenGL rendering against WebGL rendering in the browser.
Architecture:
- Compiles 18 KiCad GAL source files from the kicad submodule
- Uses template-based private member accessor (safer than #define private public)
- Generates shader C++ files from GLSL (10 shader pairs for SMAA AA)
- Minimal stubs for KiCad dependencies (PGM_BASE, ADVANCED_CFG, etc.)
Test coverage:
- 11 scenarios testing ~19% of GAL API
- basic-lines, line-widths, circles, arcs, rectangles, polygons
- alpha-blending, transforms, grid-cursor, segments, complex-scene
Key insights documented:
- GAL uses world-to-screen transformation requiring 1:1 pixel mapping
- FBO reading required for clean screenshots on macOS
- Layer depth needed for proper z-ordering in complex scenes
