- Add comprehensive README documenting all 28 GAL test scenarios - Document known limitation: DrawBitmap uses legacy OpenGL immediate mode (glBegin/glEnd) incompatible with shader-based test harness - Add shader accessor for DrawBitmap workaround attempt - Clean up debug code from bitmap scenario The DrawBitmap limitation is acceptable because: - It's primarily used for reference images in schematics - WebGL port will need its own bitmap rendering implementation - All other 69 GAL methods are fully tested 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
