d2f1a496f5 feat(webgl): Replace legacy GL with modern OpenGL ES 3.0 
Major refactoring to remove ALL legacy OpenGL immediate mode calls from
WEBGL_GAL and replace them with WebGL 2.0/OpenGL ES 3.0 compatible code.

Key changes:
- Add MVP matrix uniform support (replaces glMatrixMode/glOrtho/glLoadMatrix)
- Add matrix math helpers (computeOrthoMatrix, multiplyMatrix4x4, etc.)
- Replace glBegin/glEnd/glVertex with vertex manager pattern
- Rewrite DrawCursor to use vertex manager and DrawLine() calls
- Rewrite DrawBitmap to use vertex manager with SHADER_FONT mode
- Replace glEnableClientState with glVertexAttribPointer
- Replace glDrawBuffer with glDrawBuffers (WebGL 2.0 API)
- Add fullscreen_quad.cpp/h for compositor Present()
- Update SHADER class with mat4 uniform support
- Add MultiplyMatrix() to vertex_manager for Transform()
- Remove all legacy GL stubs from wasm_stubs.cpp

Build now completes with FULL_ES3 mode (no LEGACY_GL_EMULATION).
Remaining issue: wxWidgets GL library calls glColor3f internally.

6c2cf85177 feat(webgl): Fix GL initialization and add GLSL ES shader conversion 
Progress on WEBGL_GAL rendering:

- Fix GLImmediateShim initialization by adding GL function dependencies
  (glBegin, glEnd, glVertex2f, etc.) to $GLImmediateShim__deps
- Add COLOR4D(EDA_COLOR_T) constructor stub to wasm_stubs.cpp
- Fix GAL context locking - add LockContext/UnlockContext calls
- Add exception catching to build (-sNO_DISABLE_EXCEPTION_CATCHING)
- Create GLSL ES 1.00 shader converter in generate_shaders.py:
  - Remove #version 120 directive (ES 1.00 default)
  - Add precision highp float/int qualifiers
  - Convert int * float to float literals (2 * x -> 2.0 * x)
- Update build script to clean output files for linker flag changes
- Add console capture to test spec for debugging

Current status:
- WASM builds and loads successfully
- GLImmediateShim initializes correctly
- WEBGL_GAL creates successfully
- Shader compilation fails due to Emscripten LEGACY_GL_EMULATION
  prepending code that conflicts with custom shader precision

Next: Investigate shader compilation with LEGACY_GL_EMULATION or
consider alternative approaches for GL compatibility.

c23bc974be feat(webgl): Wire up WEBGL_GAL test harness with proper canvas setup 
- 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).
