NAME

       Bio::Graphics::Glyph::broken_line - The "broken line" glyph

SYNOPSIS

         See L<Bio::Graphics::Panel> and L<Bio::Graphics::Glyph>.

DESCRIPTION

       This glyph draws a straight line whose segment is shifted ("sheared") up or down. There
       can be an optional "break" (two diagonal lines passing between the main line and its
       segment).  Either the left or the right side of the main line can be absent.  The line can
       be of fixed size or extend to take up all available space.

       In addition to the common options, the following glyph-specific options are recognized:

         -extend       Whether to extend the line or   1
                               to keep the length fixed (1 or 0)
