the defaults for properties are set in src/graphics.h.in. search for markersize inside this file and you'll find it. > Anyone on the maintainers list familiar with graphics, should scripts be > setting any absolute sizes anymore?

I'm not sure where the default came from, and also I'm not sure that marker size is consistent across backends. for the open-gl based backends (currently fltk) markersize is in points (i.e. 1/72 inch), assuming 72dpi for the screen.
