This solves an issue when both linear gizmos happen to be at the same position.
In this case the gizmos became fairly unusable because they overlapped a lot.
They can still overlap of course, but it's more likely that they start at the
same position than that they end at the same position.
Note, when using a transform gizmo, the collision between the scale and
translate gizmo is resolved already. The issue only happens when two independent
Linear Gizmo nodes are used.
