# Driver reports tool size as an area measurement.

# using size = sqrt(22 * rawToolArea + 0) * 9.2 + 0.

# Pressure
# Driver reports signal strength as pressure.
#
# A normal thumb touch while touching the back of the device
# typically registers about 100 signal strength units although
# this value is highly variable and is sensitive to contact area,
# manner of contact and environmental conditions.  We set the
# scale so that a normal touch with good signal strength will be
# reported as having a pressure somewhere in the vicinity of 1.0,
# a featherlight touch will be below 1.0 and a heavy or large touch
# will be above 1.0.  We don't expect these values to be accurate.
