Hi Matt,
I agree that there should be a simple mechanism to define your
own marker types. The function to do that is nearly there in TGX11,
but this is the wrong place to do the job. The mechanism must obviously
work for the screen and Postscript.
I think the best place is to add a new function in TStyle with
the possibility to add new markers (a la TGX11) or (why not?)
the possibility to draw any user defined object (derived from TObject).
I will look into this possibility.
