// Sending a down/move event with a pressure of 0.0 indicates the actual pressure is unknown.

// For hover events, the pressure value is treated as a 1.0 to 0.0 range of distance from the touch
// surface where 1.0 is the farthest measurable distance and 0.0 is actually touching the display
// (which is invalid for a hover event). Reporting distance 0.0 for a hover event indicates the

// Pointer ID is an opaque ID that must uniquely identify each active touch on screen. It must
// remain constant through any down/up/move/cancel events involved in a single touch interaction.
