feat(webgl): Add 4 new GAL test scenarios for expanded coverage
Expand test coverage from ~19% to ~25% of GAL API with modular scenario files: - bezier-curves: Tests DrawCurve() with S-curves, waves, hearts, and control points - arc-segments: Tests DrawArcSegment() with thick arc strokes (PCB trace style) - segment-chain: Tests DrawSegmentChain() with zigzags, spirals, sharp corners - group-caching: Tests BeginGroup/EndGroup/DrawGroup for cached geometry Architecture: - New scenarios in separate files under scenarios/ - Forward declarations in main gal_test_scenarios.cpp - CMakeLists.txt updated to compile new scenario modules Also: - Remove unused build-wxwidgets-native.sh (using system wxWidgets) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

/**
|
||||
* Group Caching Scenario
|
||||
*
|
||||
* Tests GAL group/caching methods:
|
||||
* - BeginGroup() / EndGroup() - define cached geometry
|
||||
* - DrawGroup() - render cached geometry
|
||||
* - ChangeGroupColor() - modify group color
|
||||
* - ChangeGroupDepth() - modify group depth
|
||||
*
|
||||
* Groups allow geometry to be cached in GPU memory and redrawn
|
||||
* efficiently, useful for static elements that don't change often.
