feat(gal-test): Add 100% GAL API test coverage (28 scenarios)
Expand GAL native test harness from 24 to 28 scenarios covering all 70 GAL methods. New scenarios: - scenario_text_attrs.cpp (24): Text attribute APIs (SetGlyphSize, SetFontBold/Italic/Underlined, SetTextMirrored, justification) - scenario_glyphs.cpp (25): DrawGlyph/DrawGlyphs with stroke glyphs - scenario_bitmap.cpp (26): DrawBitmap with test patterns - scenario_transform.cpp (27): Transform() API documentation Additional API coverage in existing scenarios: - Flush() in test harness - SetFlip(), SetRotation() in screen-transform - SetDepthRange() in depth-testing - GetGridPoint() in grid-native New stub files: - kifont_stub.h: STROKE_GLYPH factory functions for letter glyphs - bitmap_base_stub.h: Test pattern generators (checkerboard, gradient) Note: Bitmap scenario shows empty panels - DrawBitmap uses legacy OpenGL immediate mode (glBegin/glEnd) which doesn't work while shader is active. This is a known limitation when testing outside KiCad's VIEW rendering flow. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

/**
|
||||
* Glyphs Scenario
|
||||
*
|
||||
* Tests GAL DrawGlyph() and DrawGlyphs() methods using STROKE_GLYPH.
|
||||
*
|
||||
* STROKE_GLYPH inherits from std::vector<std::vector<VECTOR2D>>, where each
|
||||
* inner vector is a stroke path (pen down to pen up). DrawGlyph() for stroke
|
||||
* glyphs internally calls DrawPolylines() to render the strokes.
|
||||
*
|
||||
* This scenario demonstrates:
|
||||
* 1. Single glyph rendering with DrawGlyph()
|
||||
* 2. Multiple glyph rendering with DrawGlyphs()
|
||||
* 3. Different glyph sizes and positions
|
||||
* 4. "KICAD" text spelling using stroke glyphs
