/**
|
||||
* 只读探针：把 Spine View 面板里每个控件的**真实坐标/尺寸**和父子关系打出来，
|
||||
* 用来查"列表里的内容跑到面板外面"到底是谁的坐标不对。不改任何状态。
|
||||
*
|
||||
* 依据（都不是猜的）：
|
||||
* - Actor 的 9 个 float 字段按 libGDX 声明顺序 = x, y, width, height, originX, originY,
|
||||
* scaleX, scaleY, rotation（`javap -p dl` 里就是这一串 float）；
|
||||
* - `dl.init()F` = getHeight（面板日志里一直在用），用来交叉验证哪个字段是 height；
|
||||
* - `eX.V(Z)V` = WidgetGroup.setFillParent、`eX.StackMapTable()V` = layout、
|
||||
* `et.C(Z)V` = Table.setClip、`do.D()Lhq;` = Group.getChildren（取自字节码反查）。
