linestyle option for FancyArrowPatch and similar commands
I was wondering why there are inconsistent values for the 'linestyle'
option in matplotlib.backend_bases.GraphicsContextBase. The values
allowed are 'solid', 'dashed', 'dotted' and 'dashdot', aside from tuples.
Compare this with the options available for the usual pyplot.plot()
command, where the linestyles are '-', '--', '-.', ':', etc.
Is there a specific reason for the difference in the options? It doesn't
seem too hard to add the options '-', '--', etc to the
GraphicsContextBase class - one only needs to add these to a dict at
