1. Rewrite liquidglass.frag with SDF-based refraction algorithm (rounded-rect SDF, surface height profile, Snell displacement) 2. Add three-stage rendering pipeline in GlassEffect.qml: blur MultiEffect → glass ShaderEffect → shadow MultiEffect 3. Move outer shadow from shader to MultiEffect (Stage 3) with autoPaddingEnabled for shadow overflow beyond item bounds 4. Simplify glass parameters to 7 knobs: bezelWidth, thickness, ior, specularOpacity, tintOpacity, shadow, radius 5. Update DConfig: remove obsolete keys, add glassSpecularOpacity, glassTintOpacity, glassShadow with new default values 6. Update RoundBlur.qml to remove obsolete property references 7. Update test_glass helper and Main.qml for new parameter set 8. Add shadow/ior/thickness render difference tests, remove obsolete highlight/dispersion/light-angle tests Log: Rewrote glass effect shader and added three-stage rendering pipeline with MultiEffect-based outer shadow Influence: 1. Test glass effect rendering with various parameter combinations 2. Verify glass effect toggle between liquid glass and traditional blur 3. Test backdrop blur with rounded corners in windows and panels 4. Verify lockscreen RoundBlur still works with glass disabled 5. Test DConfig parameter changes take effect at runtime feat: 重写玻璃效果并添加三阶段渲染管线 1. 重写 liquidglass.frag，采用基于 SDF 的折射算法 （圆角矩形 SDF、表面高度剖面、Snell 位移） 2. 在 GlassEffect.qml 中添加三阶段渲染管线： 模糊 MultiEffect → 玻璃 ShaderEffect → 阴影 MultiEffect 3. 将外阴影从 shader 移至 MultiEffect（第三阶段）， 通过 autoPaddingEnabled 实现阴影溢出 item 边界 4. 精简玻璃参数为 7 个：bezelWidth、thickness、 ior、specularOpacity、tintOpacity、shadow、radius 5. 更新 DConfig：移除过时 key，新增 glassSpecularOpacity、 glassTintOpacity、glassShadow 并使用新默认值 6. 更新 RoundBlur.qml 移除过时属性引用 7. 更新 test_glass helper 和 Main.qml 适配新参数集 8. 新增 shadow/ior/thickness 渲染差异测试，移除过时的 highlight/dispersion/light-angle 测试 Log: 重写玻璃效果着色器并添加基于 MultiEffect 外阴影的 三阶段渲染管线 Influence: 1. 测试玻璃效果在不同参数组合下的渲染 2. 验证玻璃效果与传统模糊之间的切换 3. 测试窗口和面板中带圆角的背景模糊 4. 验证锁屏 RoundBlur 在 glass 禁用时仍正常工作 5. 测试 DConfig 参数变更在运行时生效

Summary
Rewrites treeland's glass effect shader and adds a three-stage rendering pipeline for improved visual quality and shadow overflow.
Changes
misc/shaders/liquidglass.frag): SDF-based refraction algorithm (rounded-rect SDF → surface height profile → Snell displacement → specular → inner shadow → inner rim → tint → alpha). Outer shadow removed from shader.GlassEffect.qml): blur MultiEffect → glass ShaderEffect → shadow MultiEffect. Stage 2 usesopacity: 0+layer.enabledfor texture sampling. Stage 3 usesautoPaddingEnabledfor shadow overflow beyond item bounds.org.deepin.dde.treeland.user.json): Removed obsolete keys; addedglassSpecularOpacity,glassTintOpacity,glassShadowwith new defaults.Parameter defaults
