- 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)

- Fix coordinate system for 1:1 pixel mapping (was using nm scale)
- Set worldUnitLength to 1/96 to match native test setup
- Add SetLookAtPoint and SetZoomFactor for proper view transformation
- Fix glDrawBuffers for WebGL 2.0 (array index must match attachment)
- Add legacy_gl_stubs.js for wxWidgets compatibility
- Add isReady() check to prevent race condition in Playwright tests
All 28 GAL test scenarios now render correctly in WebGL.

- Add wasm_stubs.cpp with WASM-specific stub implementations for
COLOR4D::BLACK/WHITE, GLU tesselator, PGM_BASE, and other KiCad
dependencies
- Update Makefile to include KiCad sources (GAL base class, display
options, HiDPI canvas) and test scenarios
- Fix kiglew.h to define GLEW guard (__glew_h__) preventing conflicts
with Emscripten's GLEW header
- Update test HTML to create canvas before module load (MODULARIZE
requires passing canvas in Module config, not preRun)
- Update Playwright tests to find canvas elements correctly
- Add #window-container for wxWidgets GL canvas support
Build produces 8.4MB WASM with full WEBGL_GAL implementation.
Tests pass but rendering still shows dark output (debugging in progress).

Add complete test infrastructure for WebGL GAL visual regression testing:
- scripts/test-gal-regression.sh: Master script that builds both backends,
runs tests, and performs two-level comparison (native vs baseline,
webgl vs native)
- scripts/build-gal-webgl-test.sh: WASM build using Makefile with em++
- tests/gal-regression/wasm/: WebGL test harness (stub WEBGL_GAL)
- tests/e2e/gal-webgl.spec.ts: Playwright test for screenshot capture
Fix Homebrew Emscripten environment in scripts/common/env.sh:
- Set EMSDK_PYTHON for Python 3.10+ (em++ reads this, not $PYTHON)
- Add bundled LLVM to PATH (Emscripten needs its clang with WASM backend)
Verified: Native vs Baseline passes (28/28), WebGL generates blank
screenshots as expected (WEBGL_GAL implementation is Phase 2).
