/* test_p1p2p3_repro.c — 宿主复现并校验 P1/P2/P3 三个真机问题的修复（离屏 480x720，16bpp）。
|
||
*
|
||
* 方法：#include 真实 `hello.c`（改 hello 的 main 名），直接驱动 demo 的真实函数
|
||
* （demo_paint / d_redraw / demo_touch_down / demo_rebuild_to），对 back_buf 做像素断言。
|
||
* 这样测的是「真实 demo 代码 + 真实 SDK」，不是模拟桩。不依赖 /dev/fb0 / 字库 / launcher。
|
||
*
|
||
* 覆盖：
|
||
* P1 z-order 叠层：圆形进度条(实时重绘)与 FAB 浮层重叠时，局部重绘不再清掉/盖住 FAB。
|
||
* 旧 d_redraw=清底+只画单控件 → FAB 重叠区被抹成背景；新 d_redraw=d_paint_region
|
||
* 重画重叠区完整 z 栈（内容→标题→slider值→chrome）→ FAB 保持。
|
||
* P2 list 焦点：命中非 list 区域时释放列表焦点、切页滚动（不再沿用旧焦点继续滚列表）。
|
||
* P3 list 脏区：W_LIST 绘制已裁剪到视口；滚动(非整行偏移)+选中行不再向标题间隙/底缘下泄漏
|
||
* 填充（此前泄漏会标脏并上屏 → 标题栏/底部残留）。
|
||
*
|
||
* 编译（宿主 gcc，链真实 gfx/sys/theme/vol/log/widget/input/activity/dialog/ime/img/config/
|
||
* notify/ipc + 打桩 font/global(test_host_stub) + stb_image）：
|
||
* gcc -Wall -Wextra -DMEOW_UI_HOST_TEST -Dmain=hello_app_main \
|
||
* -o test_p1p2p3_repro test_p1p2p3_repro.c test_host_stub.c \
|
||
* meow_ui_gfx.c meow_ui_sys.c meow_ui_theme.c meow_ui_vol.c meow_ui_log.c \
|
||
* meow_ui_widget.c meow_ui_input.c meow_ui_activity.c meow_ui_dialog.c meow_ui_ime.c \
|
||
* meow_ui_img.c meow_ui_config.c meow_ui_notify.c meow_notify_ipc.c stb_image.c \
|
||
* -I. -I../hello_app -I../meow_launcherd -pthread -lm
|
||
* 运行：MEOW_UI_DUMP=/tmp/repro.ppm ./test_p1p2p3_repro （optional，dump 最终屏幕）
|
||
*
|
||
* 修复前（无 P1/P2/P3 修法）预期输出：RESULT: 4 FAIL(S)；
|
||
* 修复后：RESULT: ALL PASS。
