MWrapParticlesQ CoordinateList.l,NumPoints.l ; Bring particles in from opposite edge to which they left

Does the same as MWrapParticles except with X.q,Y.q data. Each coordinate pair is
two longwords, and the upper word of each longword is taken to be the integer
coordinate. The decimal part is ignored. Particles will be wrapped around left,
right, top and bottom edges.
