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.
