Simplify ninja code

Browse source 
Reasoning this change is correct:

* `OldPos` is set to `m_Pos` in line 260
* `m_Pos` is not modified in between line 260 and 272 (only `m_Core.m_Pos` gets modified)
* Therefore line 269 `Dir = m_Pos - OldPos` is always `vec2(0.0, 0.0)`.
* And line 271 `Center = OldPos + Dir * 0.5 = OldPos`.

So we can pass `OldPos` to `FindEntities` in line 272. Using `OldPos` here instead of `m_Pos` makes it clear, that we use the position before the move, even though `m_Pos` also still holds the old value.
