This glyph draws genomic features as rectangles. If the feature
contains subfeatures, then the glyph will draw a single solid box that
spans all the subfeatures. Features can be named with a label at the
top, and annotated with a descriptive string at the bottom.

=head1 NAME
Bio::Graphics::Glyph::box - The "box" glyph
=head1 SYNOPSIS
See L<Bio::Graphics::Panel> and L<Bio::Graphics::Glyph>.
=head1 DESCRIPTION
This is the most basic glyph. It draws a filled box and optionally a
label. It does *NOT* draw subparts, and so is useful for semantic
zooming when one is zoomed out too far to see substructure.
=head2 OPTIONS
The following options are standard among all Glyphs. See
L<Bio::Graphics::Glyph> for a full explanation.
Option Description Default
------ ----------- -------
-fgcolor Foreground color black
-outlinecolor Synonym for -fgcolor
-bgcolor Background color turquoise
-fillcolor Synonym for -bgcolor
-linewidth Line width 1
-height Height of glyph 10
-font Glyph font gdSmallFont
-connector Connector type 0 (false)
-connector_color
Connector color black
-label Whether to draw a label 0 (false)
-description Whether to draw a description 0 (false)
-strand_arrow Whether to indicate 0 (false)
strandedness
-hilite Highlight color undef (no color)
