subtree pull sdk 来自主仓 pub/sdk（主仓 commit 68ce46a 等）。新增： - 布局引擎 meow_ui_box / 动画基座 meow_ui_anim / 滚动物理 meow_ui_scroll - §6.4 事件分发形式化 / W_LISTVIEW 虚拟化多行 / meow_str 字符串资源 i18n - sb_icons 动作图标扩充 + topbar 位图图标 / meow_img_downscale - tools/ 图标生成脚本与 SVG 源 - 对应宿主 test_*.c 与 demo_box_scroll.c build_sdk.sh 冲突解析：保留公开仓自包含版（vendored meow_font + -Iinclude -I.）， OBJS 手工并入 4 个新模块（meow_ui_box/anim/scroll/str）。保留 vendored meow_font.c/ meow_ipc.h/meow_font.h/meow_notif.h，剔除宿主测试二进制与编译产物。

"""gen_action_icons.py — 从 Material Symbols Rounded 官方 SVG 生成 sb_icons.h 位图动作图标。
|
||
|
||
背景：MeowOS SDK topbar（W_TOPAPPBAR）动作此前用字体码点（⚙↻⌕）绘制，4k 字库无这些码点→豆腐。
|
||
正确路线 = 位图图标：与状态栏同一张 sb_icons[]（Material Symbols Rounded 32x32 单通道 alpha），
|
||
动作项经 meow_topappbar_set_item_icon(w, idx, MEOW_ICON_*) 指定索引后即画位图。
|
||
|
||
版权/来源：图标位图源自 google/material-design-icons 的 Material Symbols Rounded（Apache-2.0）。
|
||
本脚本只做下载（或读缓存）+ 栅格化成 32x32 单通道 alpha + 拼接 C 数组。
|
||
|
||
生成方式：svg（24px 网格，viewBox 0 -960 960 960）→ cairosvg 512x512 → LANCZOS 降到 32x32
|
||
取 alpha 通道（每像素 0..255 亮度/alpha，与状态栏同源——绘制颜色由调用方主题表提供）。
|
||
用 FILL=1（实心）以匹配现有状态栏图标的实心风格（WiFi/BT/BATT 均为实心）。
|
||
|
||
可复现性：SVG 缓存于本目录 icons_src/{symbol}_fill1_24px.svg（缺则联网下载，命中缓存即断网可跑）；
|
||
栅格参数（512/32/LANCZOS/FILL=1）固定 → 重跑输出一致。
|
||
|
||
用法（在 patch_v2/sdk/ 下）：
|
||
python3 tools/gen_action_icons.py # 用 venv 的 cairosvg 运行
|
||
依赖：Python3 + Pillow + cairosvg（isolated venv：python3 -m venv <v> && <v>/bin/pip install cairosvg）。
|
||
输出：重写 patch_v2/sdk/sb_icons.h——保留现有 15 个状态栏位图（0-14，原样），追加 15 个动作
|
||
图标（15-29），索引兼容（既有索引不变，只追加）。
