MPlotParticles CoordinateList.l,NumPoints.l[,Colour.b] ; Plot lots of points from an X.w,Y.w table of coords

Performs multiple Plot operations to the currently used chunky Bitmap, in the
current Ink colour or the specified colour. CoordinateList.l should point to
memory containing a list of coordinates. The coordinates should normally be within
the bitmap's dimensions. The list should contain X.w,Y.w pairs. The total number
of points that are to be processed is passed as NumPoints.l, and notice that this
is a longword value and allows for more particles than you probably have the
memory capacity for, although there is a limit of about 2^29 particles.
Coordinates are taken from the list and the pixels are plotted to those locations
on the bitmap, in the colour being used or specified. When MParticleMode is set
to MSimpleReMapMode or MReMapMode, points will be simple or complex remapped
respectively. In MReMapMode, the specified colour or ink will be used as the
source. In MSimpleReMapMode the destination pixels will be simple-remapped
regardless of the specified or currently used colour.
