Coverage-mode codes written to TEXCOORD2.x. Must match UniText_Coverage.hlsl.
public static floatWithCorner()
Packs a corner code into the mode: mode + 16 × code, where code is 0 (legacy perpendicular field), RoundCorners, or a Sharp miter limit quantized to 0.25 steps (1..8). Unallocated UV2 reads as 0 → Fill + legacy, so plain text is unaffected.
public static const floatFill
public static const floatStroke
public static const floatShadow
public static const floatInnerShadow
public static const floatRoundCorners
Corner code for round (Euclidean) corners; 0 = legacy perpendicular field (plain fill).
