# In order to keep things simple, we just call the X11 xrandr application
# when we receive notification of a display change instead of reimplementing
# it inside our Guest Additions client application.  This saves us among
# other things having to find ways to build and link the C code on systems
# which do not support RandR 1.2.  We wrap the call to xrandr in this script
# so that we can make any fiddly adjustments to the call which may be needed.
