[BUG] Line::getPointAlongLine (ValueType) divide by 0 for degenerate lines

In Line::getPointAlongLine (ValueType distanceFromStart) there’s a divide by 0 produced if start and end are the same. Line::getPointAlongLine (ValueType, ValueType) handles the degenerate case correctly, as does Line::getPointAlongLineProportionally.

Here’s the current implementation:
Point<ValueType> getPointAlongLine (ValueType distanceFromStart) const noexcept { return start + (end - start) * (distanceFromStart / getLength()); }

Thank you for reporting.
