NAME

       Ace::Graphics::Glyph::arrow - The "arrow" glyph

SYNOPSIS

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

DESCRIPTION

       This glyph draws arrows.  Depending on options, the arrows can be labeled, be oriented
       vertically or horizontally, or can contain major and minor ticks suitable for use as a
       scale.

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

         Option      Description               Default
         ------      -----------               -------

         -tick       Whether to draw major       0
                     and minor ticks.
                     0 = no ticks
                     1 = major ticks
                     2 = minor ticks

         -parallel   Whether to draw the arrow   true
                     parallel to the sequence
                     or perpendicular to it.

         -northeast  Whether to draw the         true
                     north or east arrowhead
                     (depending on orientation)

         -southwest  Whether to draw the         true
                     south or west arrowhead
                     (depending on orientation)

       Set -parallel to false to display a point-like feature such as a polymorphism, or to
       indicate an important location.  If the feature start == end, then the glyph will draw a
       single arrow at the designated location:

              ^
              |

       Otherwise, there will be two arrows at the start and end:

              ^              ^
              |              |
