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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
