stroke

A streak between two surface points, tapering toward its end. A fringe draws a film edge round it; a fluid's drip goes without, since a fringe dithered a 1 px streak.

Vars
fringe	Whether a film edge runs round it.
span_across	Pixels round the limb from its start to its end.
span_squared	Its length in pixels, squared.
span_up	Pixels up the limb from its start to its end.
start_along	The h it starts at.
start_theta	The theta it starts at.
taper	How much of its width it loses by its end.
width	Its width at the start, in pixels.
Procs
New	Starts a streak.
thickness	Body within the streak's half width of its line, a film fringe 0.7 px past that.

New
(limb, /list/start, /list/finish, width, taper, fringe)

Starts a streak.

Arguments:

limb: The DIRT_LIMB_* define it lies on.
start: Where it starts, list(theta, h).
finish: Where it ends, list(theta, h).
width: Its width at the start, in pixels.
taper: How much of its width it loses by its end.
fringe: Whether a film edge runs round it.

↑
thickness
(theta, along)

Body within the streak's half width of its line, a film fringe 0.7 px past that.
