Resolves all 6 open unknowns for Tasks 2–6 of the LayoutDesc importer plan:
1. Edge-anchor flags: 1=near-pin, 2=far-pin, 3=float-center, 4=stretch.
The plan's assumption of 4="pinned to that side" is corrected — 1 is
the near-pin, 4 is stretch (both sides). Revised ToAnchors signature given.
2. ElementDesc members: all are public FIELDS (not properties). X/Y/Width/
Height/LeftEdge/etc. are uint. Type is uint (not enum). States is
Dictionary<UIStateId, StateDesc>. Children is Dictionary<uint, ElementDesc>.
3. StateDesc shape: Properties is Dictionary<uint, BaseProperty> with concrete
subclasses (ArrayBaseProperty, DataIdBaseProperty, IntegerBaseProperty, etc.).
Font DID (0x1A) is ArrayBaseProperty[ DataIdBaseProperty{Value=0x40000000} ].
Font color (0x1B) is ArrayBaseProperty[ ColorBaseProperty ]. Fill (0x69) is
NOT in the dat — pushed at runtime by gmVitalsUI::Update.
4. DrawModeType enum: Undefined=0, Normal=1, Overlay=2, Alphablend=3.
No "Stretch" value exists. Vitals uses Normal(1) and Alphablend(3) only.
5. Type values confirmed from RegisterElementClass: 3=Field/container,
7=Meter→UiMeter, 9=Resizebar, 0xC=Text, 2=Dragbar, 12=style prototype (skip).
6. Inheritance chain: vitals text labels (Type=0) inherit from base element
0x10000376 in layout 0x2100003F (Type=12), which carries font DID 0x40000000.
The full per-vital sprite id tables for 0x2100006C are confirmed.
