I would also propose being able to set the drawing style to allow for
filled, wireframe, or points:
FILE FORMAT/DEFAULTS:
STYLE (enumerator)
FILLED draw as filled regions (default)
LINES draw as wireframe outlines
POINTS draw as independent points
INVISIBLE don't draw at all
e.g.
DrawStyle {
style FILLED
}
