extensionRay()

static HALF_LINE extensionRay ( const PCB_SHAPE & aSource, GRAPHIC_ENDPOINT aEndpoint )

static

The ray the shape grows along.

Runs from the fixed end through the extended one.

Anchoring on the two existing endpoints keeps the direction exact. Projecting a third point would overflow at full range. The ray also covers the shape, so drop candidates behind it.
