# rain utility
# =============================================================================
# Provides a property which can be used to control rain. Can be used to turn
# off rain in internal views, and or used with a texture on canopies etc.
# The output is co-ordinated with system precipitation.
#
# see Hawker Seahawk for an example.
#
# SYNOPSIS:
# aircraft.rain.init();
# aircraft.rain.update();
#
