Interface PressureToWidthOptions

Response curve exponent applied to pressure before lerping (p ** gamma). 1 = linear; >1 emphasizes light touches (sharper thin → thick transition); <1 emphasizes heavy touches. Default 1.6, a small bias toward heavy strokes that matches typical pencil feel without crushing the dynamic range.

Width returned at pressure 1. Default 6.

Width returned at pressure 0. Default 0.5.
