- Update wasm/Makefile to compile ALL scenario files using wildcard
- Add conditional compilation to scenario_bitmap.cpp (#ifdef __EMSCRIPTEN__)
to handle OpenGL-specific shader workaround code for native only
- Change canvas dimensions to 1600x1200 to match native baseline (2x Retina)
- Set white background color to match native screenshots
- Update gal-webgl.spec.ts to hide UI overlay before taking screenshots
- Improve test-gal-regression.sh with better ImageMagick comparison
All 28 scenarios now compile and run on both native and WebGL backends.
Native vs baseline: PASSED (28/28 matching)
WebGL rendering: In progress (primitives not yet visible)
