Stroking is vague and underspecified

[mikebmcl]

What orientation is a square cap drawn when a path trajectory is zero-length?  No concrete explanation of dashing is given.  Dashing requires breaking the path up into segments of arc length based on the dash pattern.  Stroking should be specified as the union of all pixels swept out by (dashed on) segments for each trajectory or contour in the path.  The " there is an infinite number of points along each rendered portion" statement is quite insufficient.  Does dashed arc length accumulate (or reset) when the path switches to a different trajectory/contour?

Resolved the issue of orientation by eliminating degenerate segments (and thus degenerate figures). Other issues other issues require more contemplation and seem editorial rather than design such that I'm dropping this to P3.
