Interface: StrokeContext
Defined in: pencil.ts:165
What an adaptive mode would get to look at. Populated from the opening of a stroke (and, once auto is real, updated as it develops).
It is deliberately not the raw sample list: an adaptive resolver that can see everything will end up depending on everything, and this is a seam we want to stay narrow. Speed, size, and how flat the pen is being held are the signals a human would use to tell writing from sketching at a glance, and they are almost certainly enough.
Properties
altitude
