A 2D text annotation (IfcTextLiteral / IfcTextLiteralWithExtent).
Position is in the same 2D coordinate space as SymbolicPolyline (i.e. the
floor-plan / annotation overlay's local frame after applying placement +
RTC). The text-orientation pair (cos, sin) rotates the baseline from the
+x axis. Height is the IFC font height in model units, scaled by the
project's length-unit factor so the renderer can convert directly to world
units. Alignment is the IFC BoxAlignment string verbatim
(top-left, center, bottom-right, …) — the renderer can interpret it.
