A collection of glyph decorations, e.g. arrow heads.
Use ``GlyphRenderer.add_decoration()`` for easy setup for all glyphs
of a glyph renderer. Use this property when finer control is needed.
.. note::
Decorations are only for aiding visual appearance of a glyph,
but they don't participate in hit testing, etc.
