qu_markers

Every marker Qu draws, at the size a figure actually uses.

catalog/qu_markers.qu

A marker table is only useful at working size. Printed large, every outline looks fine; at the 2-4 pt a real series uses, the question is whether two of them can still be told apart -- so each row here shows the glyph twice, hollow at 6 pt to check the shape and filled at 2.5 pt to check it survives.

Run: qu run catalog/qu_markers.qu
