DESCRIPTION

lsbackup is one of two routines that modify the application of the linestyle pattern.  If enabled, it overrides the current linestyle to guarantee that the last two pixels in a line are colored.  It takes one argument (b), a boolean.  If b is TRUE (1), backup mode is enabled.  Set resetls to TRUE when backup mode is enabled.  If b is FALSE (0), the default setting, the linestyle is used as it stands, and lines can have invisible endpoints.
