Methods
SlopPx(double, double)
Scales a base slop distance (defined at 160 dpi) to the device's
actual dpi. A non-positive dpi (dpi unknown)
leaves the base value unscaled.

Returns
WithinSlop(double, double, double)
True when a press-to-release delta stayed within the slop radius, i.e. it reads as a click rather than a drag.
public static bool WithinSlop(double dx, double dy, double slopPx)
