Rightfully so. Ideally everything should be under your control. BTW,
new symbols are fairly easy to add. Just take a look at
Basically, you just have to define one new function following the lead
of the many that are already there and one new dictionary entry in
lineMarkers. If you or anyone else defines some custom markers,
please send them my way.

Actually this is how dashes are implemented at the renderer level,
with an arbitrary sequence of on off ink in points. All that was
needed was to expose this to the user interface, which I've done with
a new method set_dashes, eg,

line.set_dashes([5,3,1,12]) # 5 on 3 off 1 on 12 off

In the next release there will be a new examples/ which
illustrates this.

Thanks for the suggestion,
