/*
 * This header file is a FreeCalypso addition to R2D.  It defines
 * the API for turning BLRR (backlight required for readability)
 * displays on and off, and for communicating different display modes
 * which may translate to different display brightness levels
 * (different backlight intensity levels) on some hw targets.
