+% Note: for whole and half notes, the "fill" curve (p_out) is offset
+% from the points that specify the outer geometry, because we need
+% to add the rounding. In contrast, the inner curve is not
+% offset, because there is no rounding.
+%
+% This means that to get a line of thick_factor * pen_thickness,
+% we need to offset the inner curve by
+% (thick_factor - 0.5) * pen_thickness or by
+% (2 * thick_factor - 1) * half_pen_thickness
