UI Widget Enhancements: - Add texture support to UICheckbox (box and checkmark textures) - Add texture support to UISlider (track and handle textures) - Add texture support to UIPanel (background texture) - Add texture support to UIProgressBar (background and fill textures) - Add texture support to UIScrollPanel (background and scrollbar textures) - All widgets now support textureId with tint color for flexible styling BgfxRenderer: - Add texture loading helpers for widget texturing - Update RHI device for texture management - Add ResourceCache texture ID support Maintenance: - Add tmpclaude-* to .gitignore (temporary Claude Code directories) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
