otrack_snap reports a single active ray, and the overlay painted only
that — with two acquired points the second vector was invisible even
while the cursor locked to their intersection. Each acquired point now
gets its own infinite dashed vector (active full strength, others at
half alpha along their cursor-relevant direction), and when a non-
active vector passes through the locked point an intersection X marks
the crossing, mirroring the OSNAP intersection glyph. Pure view-layer
change; snap math and state machines untouched.
