MDrawParticlesA AddressList.l,NumPoints.l,Buffer.l ; Draw lots of previously grabbed points, using Ptr.l's

Does the same as MDrawParticles, except that the items on the list are stored as
actual memory addresses. Each address (a longword) is the actual address in
memory to which pixels will be drawn. Many animation effects are possible due to
the time-consuming calculations being avoided in working out where in memory to
grab from. There is only one longword per item, which represents the X and Y
coordinates combined. Particles are drawn from the memory buffer pointed to by
Buffer.l, and the whole lot is done in reverse order in order to facilitate a
stack system.
