Quelltext der Seite RDesktop no-motion improvements

<source lang="diff">#
# Patch against rdesktop 1.6.0 improving behaviour of the
# `do not send motion events' command line option.
#
# a) Don't touch the local cursor if '-m' is set, i.e. don't make it
#    disappear or the like.
#
# b) Send motion-events if one of the first three mouse buttons is
#    pressed no matter what.  This allows to conveniently drag'n'drop
#    even with -m option being set.
