Remarks

Unlike DrawLine(IRenderContext, Vector2, Vector2, Color, float), which grows its thickness to one side:

• each segment is centered on the line between its two points;
• the free ends stop at their points (flat ends);
• each joint gets one square, the thickness wide, centered on the shared point with a corner along the outer bisector: it fills the gap between the two segments' flat ends into a sharp (mitered) corner. Exact for right-angle joints such as Icon's glyphs; close for others.

Unrotated segments are drawn as plain integer rectangles, so the engines can snap them to whole physical pixels. Rotated segments keep their sub-pixel position: their Destination is anchored at a whole pixel and Origin (in texels) carries the fractional rest, so consecutive segments meet exactly at their shared point. A length rounded up to whole pixels is split evenly between both ends.

With partial opacity, a joint blends over the ends of its segments.
